Thanks for your work! This is a very exciting development.

One question: currently, Emacs doesn't expose mouse motion events.  The code/docs say that it's because it generates too many events, but there are legitimate uses for that (such as showing info in the echo area or the modeline when the pointer is above a particular screen region).

The only trick I know of is to use show-help-function, which requires jumping through a bunch of annoying hoops.  Maybe now is a good time to add an option to propagate these events to lisp? Maybe there should be a high-frequency-events list of symbols that includes which events should be propagated to Lisp? One pour (add-to-list 'high-frequency-events 'mouse-motion) to enable them, for example.

Cheers,
Clément.
