My last blog post was about the new Surfulater Knowledge Tree feature that allows items in the tree to display text in bold, and italic and use background and foreground colors, so tree items can have a greater visual impact. I also hinted at an ulterior motive behind this, which I can now tell you is related to the big new feature in today’s Version 3.16.0.0 release, which is Knowledge Tree Filters.

Knowledge Tree Filters enable you to choose specific items and only those items to display in the tree. This lets you quickly drill down and locate a set of items of interest and then work with them, while everything else remains hidden out of your way. You can filter by Folder name, Article title or Tag name. For example you can elect to display only articles whose title includes “energy”. I have been using this constantly while developing and refining it, for well over a month now and I have to say I am finding it very, very useful indeed.

Let me start by showing you the new Knowledge Tree Filter user interface panel which lives at the top of the Knowledge Tree bar.

As you can see it is quite simple and hopefully self-explanatory. You pick whether you want to filter by Folder Titles, Article Titles or both and then type the text to filter on. Filtering occurs as you type with the results displayed in the Knowledge Tree.

This is a screen shot of the enhanced Knowledge Tree for the sample MyKnowledge database without any filtering applied.

Now the same tree filtered by Folder or Article Titles which contain the text “energy”.

Notice that the tree items that match the filter term “energy” have the matching text highlighted, in the same way search matches are highlighted in articles in the content window.

Only articles that include “energy” in their title are displayed. The ‘Folder-Article’ counts displayed in gray are the total number of articles in the folder, not the count of filtered matches. So the folder “Solar Power” has 4 articles, but only two match the filter and are thus visible.

Two folders “Solar Power” and “Pending Reading” do not include “energy” in their title and therefore do not match the filter as such. However they do contain articles that match and because ‘Search in: Articles’ is checked, these matching articles and thus their folders are shown. All other folders and articles are excluded or filtered out.

In the screen shot above ‘Search in: Articles’ is not checked and the filter is therefore only applied to Folder Titles. You can see that only two folders match and these are highlighted. Furthermore because the Articles filter is off no checks are performed on article titles and all articles in the matching folders are included in the results.

Knowledge Tree Filters can be used with all of the Tree views, not just the Folder (normal) view. These final two screen shots show the Chronological view filtered by “march” and the Tags view filtered by “power”.

Each Knowledge Tree view retains its own independent filter settings and filter status.

The button turns the filter on and off and the button collapses and expands the Filter panel. See the Surfulater Help topic: Power Features | Knowledge Tree Filters for more information.

As I mentioned at the start I’m finding Knowledge Filtering a most welcome new feature that lets me quickly locate and see a specific set of articles. I hope you find it as useful as I do.

Other updates in this release include support for Windows 7, several Vista specific issues fixed, an update to the Firefox Extension, updates to use new versions of third party libraries, another reduction in the Surfulater.EXE size, some more performance improvements and various bug fixes. Full details are in the Surfulater Help | V3 Release Notes topic.

This sparkling new release can be downloaded from the Surfulater Home page or Download page. We look forward to your feedback and suggestions on this new release.

I’m nearing the end of development for the next major Surfulater release which includes two important new features and I want to preview the first one for you now.

An enhancement that people have been asking for is to improve the visual characteristics of items displayed in the Knowledge Tree so that for example bold or italic text could be displayed, making specific tree items stand out from the crowd and therefore be easier to locate when scrolling or paging up and down.

I’ve actually taken this a step further and have enabled tree items to display HTML so that what you see in the content window, is what you now see in the tree. This means text foreground and background colors along with bold and italics now appear in the Knowledge Tree.

This screen shot shows an article with its Title highlighted using background and foreground colors as well as bold and italic text and its corresponding item in the Knowledge Tree with the same visual markup applied.

I’ve also highlighted some folders and other articles. One other thing to note is the article counts to the right of each folder are now displayed in Grey instead of Black, making them a bit more subtle.

You have always been able to set the images displayed for each tree item and now with the ability to set the appearance of the text, you get full visual control of tree items. Further it lets Surfulater highlight items of specific interest, as the need arises.

Apart from our users wanting this, it was needed for the other even more important new feature coming in this release, which you will hear all about soon.

The Surfulater evolution continues with the release of Version 3.15.0.0. This is another milestone release with major changes to the Surfulater code base to bring it in line with the latest Microsoft Development tools, in particular MS Visual Studio 2008 and the latest C++ Compiler. This makes Surfulater more robust and enables us to use the latest Microsoft technologies as we move forward.

I’ve also taken this opportunity to make substantial changes to the way the Surfulater code is packaged. In particular seven DLL’s have been completely removed and two more have been taken out of the Installation package. This code refactoring and repackaging removes problems caused by wrong versions of DLL’s and moves us closer to the possibility of a single .EXE file, potentially without any need for an Installer. Further it helps pave the way for a Portable USB Stick version of Surfulater. And finally it reduces the size of the Installer download file from 7.79MB to 5.67MB and the installed code footprint from 16.347MB down to 12.68MB. Substantial effort has gone into this, taking up much of our development time since the last release.

That is all below the surface, but there are good things happening above ground as well.

The most visual change in this release is how Tags are displayed in articles.

They don’t just look a lot better, but they perform better as well, in that you can now click on Tag to jump to it, in the Tags Knowledge Tree and then see and work with all the articles with that tag.

The next enhancement is the ability to change the color of text using Set Text Color, which is in addition to setting its background color.

Clicking on the button or choosing the right click context menu item changes the color of the selected text to the current color.

Clicking on the down arrow opens the color selection palette, which enables you to change the current color. Note that the current color is displayed below the A image. Restore to default is also new in this release and sets the current color back to its default value. This is also included on the Highlight Text color palette.

Another new feature is Set Title to selection which enables you to set the Title of the current article to the selected text. This is available on the right click context menu, when used on selected text.

There are times when an Article Title is not what you want and this provides a quick convenient way to change it.

If you are observant you will have noticed Web Search on the menu screen shot above.

This new feature enables you to perform a Google search using the currently selected text. Another handy time saver.

A subtle change we’ve begun in this release is the ability to make more changes to selected text without having to be in edit mode. For example the Add a Link and Remove this Link commands can now be used when not in content editing mode. As can the new Set Text Color.

Of course there is more; drag & drop can now be used during content editing to move text and images, and Copy and Paste as reciprocal ‘See also’ links can now be used in the Tags and Chronological Knowledge Tree views.

As always all of the new features and bug fixes are documented in the V3 Release Notes in the Help as well as in new and updated Help topics. Make sure you at least read the release notes.

The latest release of Surfulater is available from our Download Web page.

We’ve recently completed a major overhaul of the Surfulater home page and I hope it does a better job of conveying to people what Surfulater does and how useful it can be. Feedback welcome.

I’d like to dedicate this release to our friend and golfing buddy Neil Oram who sadly and unexpectedly passed away last Monday 20 Apr 2009. Neil was always a pleasure to be around and had many great games of golf left to play. He will be fondly remembered and greatly missed.

Articles displayed in the Search Results folder have always been a little troublesome because you had no idea what folder(s) they actually lived in, and there are times when that meta-information is important. We’ve tossed around various possible solutions to this, but have never been happy with any until just recently. During yet another brain-storming session the penny dropped that yes Search Results articles are the main problem here, but wouldn’t it be nice to know all the folders any article is in, besides the current one of course.

For those new to Surfulater you may not be aware that an article can be in as many different folders as you like, with there only ever being one real instance of any given article. This solves the age old problem of picking just “one best” folder for an article.

So after this thought sunk in, some more lateral thinking bore fruit with the end result being to add a new “In Folders” breadcrumb row to each of the article templates, as shown here.

This shows that this article is located in the Knowledge Base | Alternative Energy | Solar Power folder. Each of these three sub-folders is a clickable link which take you directly to the respective folder.

When an article is in more than one folder, each one of the locations is displayed:

In addition a link named Article is included for each folder, other than the current one. Clicking on this takes you to the article in its associated folder. This new feature lets you not only see each of the folders an article is in, but also to jump to each copy of it.

Furthermore these new “In Folders” breadcrumbs are displayed for all of Knowledge Tree views. This means that when you are viewing articles in the Tags or Chronological trees, you can now see what folders they are located in, and instantly jump to them in the Normal Folder tree view. This builds on the right click context menu item “Go to Article in Normal View” in the Tags and Chronological tree views and “Go to Article” in the Search Results folder. Each of these goes to the first article found in the Normal Tree view, whereas the new “In Folders” breadcrumbs enable you to go to any article, when it is located in multiple folders.

The final enhancement here is the update to the display of collapsed folders in the content window to match  the Articles new “In Folders” row as shown here:

Like all Article rows, the “In Folders” row can be moved up and down using Edit | Enable Template Editing. See the Help Topic: Power Features | Editing Article Templates for further information on this.
I am sure you will find these enhancements let you move around and locate specific copies of articles quicker and easier than ever before.
