The short cut commands interferer with Chrome for Mac's tab changing short cuts and this at times can be very annoying.

This turns out to be a real bummer. Firefox is affected, too. I suggest to make this a p0.

Probably not very important to many, but Alt+Command+C interferes with iWork's "copy style".

Hi,

I'm the new maintainer of ShiftIt. I don't know if you have noticed, but the development has moved to https://github.com/fikovnik/ShiftIt - please give it a try. Shortcuts are now customizable in a dialog window. If you find some other, please submit an issue directly at github.
