First of all it is pretty cool to be able to skip the synergy and
short-circuit multiple layers on the way of keyboard and mouse events. It
was pretty easy to setup once I found the right options:
EXTRA_ARGS+=" -object
EXTRA_ARGS+=" -object
EXTRA_ARGS+=" -object
EXTRA_ARGS+=" -object

The was some rough edges as well. I stress-tested it playing Stacraft 2
with a lot of mouse and keyboard events. Some of my keybindings require 2
modifiers: e.g. ctrl-shift-r. The issues I found:
- It seems some modifiers sometimes was getting stuck, so I was puzzled a
few times when I couldn't select single unit (probably shift was stuck). I
have to press all modifiers to get it released.
- At some point mouse was ungrabbed and remained this way even I could
still toggle grab state for my keyboard.
- I have 2 extra mouse buttons and the Windows 8.1 didn't seem to receive
any events for them.
