I already mentioned the really nice addition of "themes" for Google Mail. But that setting is only available (and applicable) to Gmail. Nothing else. Huh?
As much as I like what Google has done in general, they never seem to get from "beta" to "final" on things. Even when they remove "beta" (which is rare). Come on. Can't they tie the stuff together a little more cleanly? How about at least making the theme setting apply across the main applications? Is that asking too much? Geez.
