One thing I don't like about the NIS is how friends chat can be optionally closed and hidden indefinitely, but not guest clan chat! How often does one visit a second clan's chat?! More often than a friends chat?! Same goes for emotes and jukebox, I don't need access to any of those!
Jagex should let us all close whatever standard tab we want, since it's all accessible from the eight main game buttons anyway.
This was the first thing I came up with, I kinda liked it:

I think I'm going to stick with the second one, with a few tweaks of course. I especially like separating game chat and people chat, though I wish they could bring back overlaid private chat that was all text and no interface.
