Just merged this in to master, which should end being released in 2.4.x:
https://github.com/cobbler/cobbler/pull/190
The main change is the move to jQuery tabs using the UI tab widget
instead of the expanding/collapsing sections we had before. Under the
hood, there were some HTML/CSS changes to make things flow a bit
better and to give better control over the placement of some DIVs, as
well as a little bit of cleanup.
Here's a screen shot, to show how the tabs look when editing:

Let me know what you think, I've primarily tested it in Chrome 18,
Firefox 12, and IE9 (which looked surprisingly good).
Enjoy!
