Diiver, that looks fantastic! Don't even think about apologizing for it being "trivial", it most assuredly isn't.
This is the other side of UI modding that many folks are still searching for, the
graphical changes. A UI can look
completely different, just by changing graphics, yet still actually be exactly the same, layout and functionality-wise. I, for one, am very glad to see folks beginning to get into the
graphical modding of the UI. That's the area I work with by preference (if I can ever get my head around it all). Now that (more) folks are actually using this area of the forums, (and so far, everyone is being incredibly patient in trying to help others, as we always hope for and expect on our forums), I expect we'll see more and more of this type of modding. It's going to be fun!
(PS, I'll look into the whole smilie thing.)
