Yeah, I haven't been able to figure out how to make the buttons on the bar reorder.  There's 12 buttons and they are horizontal on one row.  I can't make them go 3x4 and so on by changing the pane size but would be cool if I could get it to work.

I could put it out there as a freebie and leave the code exposed if you are anyone wants to fiddle with it.  However, you might shriek in terror when you see my coding style :D

I've attached an image.  It does remember it's layout and if it's docked or not (using pickle).  You can right click in an empty space to get the floating/docked menu.  I tried to make it visually fit in with the UI.
