How did you get the DTML tag completion? Have not tried that yet but would be nice.
Real simple. On the menu bar, go to Options --> Settings (or just hit F8). In the box that pops up, click on Tag Completion. Click the ADD... button. You'll get a small Tag Completion Entry box. If you want tag completion for <dtml-comment>, type in dtml-comment (it would allow you to put the <> in, so don't worry about it). Then hit OK. It will add it to the list. You can do that for all tags (dtml, cfml, HTML, whatever) The default list is already quite extensive. Once you're done and exit out of Settings, it will work. And it will automatically alphabetize your tag completion list next time you go back to it in Settings.
Maybe we could trade custom toolbars?
Do you have the Zope tags and Zope Utilities toolbars? Those are the only ones I know of, at least the only ones I've downloaded so far. I believe I still have that zip file if your interested. Tommy Innovation: The Best Way To Predict The Future ... Is To Create It.
