I'd like to move My Messages & Mentions to be to right of menu, next to Profile tab.
That way, they'd be together, as a member's section of menu.
Doing this on a site, that has a lot of site menu items... LOL
The profile menu is simply "float: right", so adding:
.listlevel1#button_pm, .listlevel1#button_mentions {
float: right;
}though, if there are
many menu items, it may not be very nice to see at certain resolutions (buttons may start going on two lines).
