Thanks for sharing your experience, since I sounds much like mine. The program icon-adding process is so odd that I'm not sure that I can duplicate it each time. At the very least, I'd have to go back to my own notes to do it, and not rely on intuition or the program's Help.
"Looking forward to some improvements in the next version..."
As for the next version, I'm not optimistic, based on my migration from Thumbs 7 to Thumbs 9. So far, improvements between those versions have eluded me. Maybe it's because of my fairly simple needs, and that newer features are of help to other users and I haven't needed them yet. For myself, I keep finding that features that worked well for me in T7 either do not work or are harder to do in T9. This toolbar icon creation is a perfect example. Not only is it harder to do, but it's not even working correctly: As far as I can tell, there is no hovertext available for the program icons as there was in T7 (unless it's a deleted feature). (Using ThumbsPlus Std 9 SP2 Build 3946)
I know I have to have a newer version of the program to operate properly in newer operating systems, but I would go back to Thumbs 7 immediately if that were practical. I don't know if I can deal with these messes by going to Thumbs 10.
