Here is a screen shot of the new panels. As you can see the crafting panel has been redesigned quite a bit. The quest log is pretty much the same except because they added those extra buttons it expanded the size of the top bar. So any skin modification that alters the quest log, I think the only thing that would need to be corrected would be the top section of the tga file would have to be increased a little bit to allow more room for the other buttons. Other than that, I don't believe there is any other changes to the UI. If anyone else finds anything, please let us know!
Hope this helps!
