I recently dove into the world of WoW UI design, and I've had decent success so far. I've run into a problem, though...
Is there a way to create the nice top-aligned tabs like the ones seen at the top of 2.3's Interface Options panel? I don't care if they act as separate buttons instead of a tab array, as I only need two tabs. I have a sneaking suspicion that I'll have to make my own custom buttons for this, but I don't really know for sure.
I don't know exactly how it's done, but I'd just check the code of these interface options and see if it's easy to embed parts of it, or if it's possible, to use already existing functions without even modifying them, in your addon.
