Spent some time using this plugin today
What I did was to edit the .JS and replace the standard 16 gestures with my own. That way it works perfectly, but its all hardcoded by hand!
I have also edited the Gesture creator to use the space bar on the keyboard to draw points. I wanted to make symbols with the minimal amount of points and the mouse button is not as accurate as a key press!
I have also added crude multitouch!
Instead of recognising the gesture on end of mouse click I start a 1 second timer, and if the user draws something else, I restart the timer. This way the user has a 1 second delay to remove his finger and position it somewhere else and continue drawing! Works perfect too!
