No unity panel on second (external) screen?

Since it is now possible to attach my external screen without getting the xserver to corrupt, I'm working on natty with a desktop spread over the two screens.

So far when I maximize a window on the second (external) screen the titlebar will appear in the unity panel on the normal screen.
If I now want to get access to the menu I have to move the mouse all the way to the first screen.
In my opinion this isn't very efficient and really annoying, too.

So is their a idea of spreading the panel over the second screen as well or just leave the titlebar on the second screen if maximized?

Thank you very much in advance!
