it'd be nice if that were a user-settable option, ya know? You can pick your color scheme, but not your icon scheme. Sorta ghetto, there.

also, I don't think I'd consider the "relaxed" theme an option. It's majorly monochrome, which isn't good for ergonomics. It's nice having an immediate color-recognition for "this thread is old" versus "this thread is new" -- at least that's what I think.
