It would be convenient if I could press ESC in mid-gesture to cancel the gesture. For instance, while using Explorer, I accidentally issued the Minimize gesture -- but, I realized that I had done so before I released the mouse button. And, while "Minimize" is relatively harmess, it could have been something more destructive such as "Close".
Also, how about a StrokIt-Announce mailing list? This program is exceptional, and I can't wait to download the next version!
