Good work. But need to improve a lot.
Here are some bugs I've noticed so far.
1. Clashes with Hide Menubar extension. When menu bar is unchecked it looks like this [http://i46.tinypic.com/14jp7a0.jpg].
2. I read small icons are not supported. Yet when I selected small icons it became this [http://i45.tinypic.com/2dcd0mc.jpg]. Maybe a "no change" in icons would do it.
3. This is a screenshot of the customize toolbar window [http://i50.tinypic.com/xmr0g6.jpg].
4. The close button on each tab is on the far-right side. Maybe a few pixel left would look good.
