Genie (http://minnow.cc.gatech.edu/squeak/2439) is a terrific 
enhancement allowing flexible mouse/pen gesture recognition in Squeak - 
thank you to the author(s).

At one time I published a changeset and gesture dictionary which set it 
up nicely for day-to-day use. In particular I could use mouse gestures 
to jump between projects quickly. I miss this and I'm seeking help to 
get Genie working again in current images.

My notes are at http://squeak.joyful.com/Genie . Status: I'm using Ned 
Konz's monticello version, which seems to load fine in 3.9/3.8/3.7. You 
need to remove a breakpoint in the code. Gesture recognition never 
activates though. My vm seems to have the Genie plugin.

If anyone knows more and can accelerate my slow progress on this, I'd 
appreciate it!
