Thanks for the bug reports, Tim. I'll be getting these fixed shortly. I expect my computer to arrive within days (thank God) and will get to them as soon as I have it back.
Oh, btw, the UBBFriend exclusion is intentional, partly because I don't use/like it myself, and mostly because I couldn't find any good place to put it inside the table. $MainButtons was considered, but it stretched that line out to insane lengths, especially when combined with other hacks like calendar/memberlist. And leaving it floating outside the table would go against the principle of CH. Feel free to hack it in yourself, but I have no plans of putting it back into the "official" code.
