You can integrate web content or whatever. Great. Just change the proportions and positions of the windows to how it used to be, and cover up the background with a static image.

The new friends box is too big. The chat box is too small and badly positioned. Nothing feels centered, and it's very annoying.

Mouse wheel scroll performance is even more spotty than it was before.

The sound when clicking tabs is bizarre. Please remove the "dream"/swishy sound effect and just leave the clunky, clacky sound. Or the other way around, if you really must. Both of them combined is strange. Also, the mouseover sound is too big for a simple mouseover.
