Okay, from what I've seen and heard, IPB 2.1's Admin CP uses tabs to separate each admin functions into neater categories.

Well, I just had this inspiration: perhaps it could be possible that we could organize tabs in our own way, so it would be suit for us, if we don't like the current category positions.

Just a thought.

and we can do this by editing admin_pages.php?

a mod will most likely be made.

Via Admin CP, actually. Through a settings pane which opens in the new window, they can set admin functions tabs and create tabs.

Would be a nice feature to have. And a more custom one.
I'll give it my +1

a mod will most likely be made.

Too complex to be made a modification, though. Someone might make a buggy one and could potentially destroy all access to the Admin CP.
