Excellent Rated 5 out of 5 stars

Excellent extension! I love that you can drag a group from one window to another, and it retains it's structure. It's so much easier to navigate large amounts of tabs now.

I think the next logical step would be to allow tab thumbnails to be displayed on selected tabs or groups?
