I loved StrokeIt and this would be an amazing alternative if it weren't for the fact that it is lacking a whitelist/blacklist option.
In StrokeIt, by design, it would only activate in programs you had it set to.
High Sign activates in programs whether or not they have any actions assigned to them.
For example, I have gestures setup ONLY for Windows Explorer yet when I am in Firefox the gesture system still seems active (they just do nothing).
The problem with this is that it seems to 1) Mess up games that are played in full screen; and 2) override other gesture systems (such as FireGestures in Firefox).
I would appreciate this feature (or information on where to locate it if it does exist already). Also I am on Windows 7 64. Just thought I would mention it.
Thanks in advance, will keep an eye on this.
