We recently added localization support to Ghost Croquet!
In doing so, I have also improved the localization system that I use in my projects (and perhaps you could too).

So I've had this idea for an AutoHotKey script that could turn motions from any pointing device (mice, trackballs, trackpads, etc.) into custom actions.
I guess you might call them gestures?
