First of all, tried the new version (v1.111.01) and love it! I can make the .lnk extensions disappear in folders, and arrange icon groups by using adjustable spacers. Didn't have any issues using my existing bar definition file. Wonderful!
There is a bug related to mouseover hints for folder items, though: The hint always shows the folder path and not what I enter in the "Hint" field. Just wanted to let you know.
Oh, and if you have room for a feature request, too: It would be great if nodes could override the caption settings, too, and not only the icon settings.
