"Mark Forum Read" button placement confusing

[zeg]

Just a comment / suggestion: I find that because the "Mark Forum Read" button on the forum list is a similar icon and identical placement to the "Go to first unread" button on the topic list page, I frequently hit that by mistake when I'm scanning for new topics of interest and switching between forums.  It's kind of a pain, since it does basically the exact opposite of what I want... While some of this is my carelessness, I think it'd be more user-friendly for this to be in a different location.

Also, is there any way to undo that action so I don't have to try to remember which threads I read when?

Thanks.
