Hey, I'm gonna be pushing out the Alpha version for public use if want to try it out. It's functional, but has some bugs. I've just been pretty swamped IRL and haven't had time to work on any of this stuff, but you've been waiting for much too long already.

It's by default bound to [X] to activate/deactivate the timer and [0] (zero) to turn it on and off. These can be changed under Tools->Options->Key Map. You can also modify the duration of the timer in the component's configuration options.
