Like hamsterdecombat said, Think is a great idea but it needs more keyboard support for it to truly become a part of my workflow. I don't want to have to change to Thin using command tab and then have to use my mouse. A program like this is for power users and power users use the keyboard. The "illuminate" jargon is also silly since it's nothing more than an app switcher.

This needs to replace command-tab to be truly useful.
