Yeah, this feature would be quite helpful. Of course, it should be deselectable for those people who never draw a gesture wrongly. But I would select it for sure, because I want to know if StrokeIt does the thing I want it to. Since I ve added some personal gestures that may be similar to some default ones, I feel slightly unsure with Strokeit. I cannot check, if a particular gesture is already used and what for, nor if StrokeIt has learned enough to distinguish my "alpha" from the default "K" surely. So I´d feel much better recognizing immediately, if something e. g. has been cut-out or if it´s deleted :).
It´s not only StrokeIt, wich has to learn ... In the current version I can EITHER get feedback within the "learning" modus OR use the gestures. To put this together would improve even this great program!
