As for Diablo, yes, it's not one to go to yet. I've seen way too many problems with it, and downgraded from it myself after suffering through many of those. As for the UI stuff, I can help with that as I'm a part time UI designer. I can't code in the languages required to build the UI's, but I can help with the actual design and layout elements, as that's where I typically focus most of my time.

As for good UI designs, I like this one for the wireless icon in the status bar:

That example really is nice, and aside from a few minor changes to the icons (for easier viewing of the variations), I think it's a good idea. I also suggested a few other UI improvements to the wireless interface in another thread. If someone wants me to, I can do some mockups so you can see the changes I've suggested.
