This morning I finished working on the tutorial, including the interactive screenshots, which will also be on the main Transformer Website. It took longer than I expected, because the originals were done with a pre-release (0.9) version of the Image Markup Tool, using a file format which can't easily be converted to any of the release versions, and in any case much has changed in the main interface. In the process of doing this, I also:

• Found and fixed a bug in the column-sorting code, which was supposed to be sorting by length of items for Find and Replace items, but was actually sorting (most of the time) alphabetically.
• Fixed a long-standing annoyance with column sizing in the TTntListView control that displays the sequence items. There's no onresize event for column headers, so they can end up being sized too wide for the control. Now they resize themselves appropriately when you exit the control, or click anywhere on it, which is better than nothing.
• Tweaked a couple of other resize functions, which were causing scrollbars to disappear in some extreme circumstances.
• Fixed a label which should have been updated before.

With luck, I can do a release of the app tomorrow, and then focus on reworking some of the code using threads, to enable monitoring and killing of JavaScript processes that run too long or get into endless loops.
