Thanks for the quick feedback! As a quick update, I threw together a todo app that also describes some of the basic functionality of Falcon. Check it out: http://jsfiddle.net/stoodder/2ZX52/20/
If you have any technical questions post them here. All bugs should be reported on http://facebook.com/GetGroovr as that is checked on a semi-regular basis.
Groovr is technically legal to use via black magic. Please report any and all bugs so we can get this shit fixed before the first official release.
