Screencast Keys Addon
=====================
While doing some tutorials, realized that when working fullscreen you often lose perception in how much time passed, resulting in unnecessarily long videos.
To tackle this, today I implemented a 'Elapsed Time' feature, with options for color/alpha, size, and reset (to restart the timer without restarting the script).
Thanks to Campbell Barton for guidance, ideas, and just being awesome.
