Mark Read/Lock UnRead
 

I don't know if this is possible, but I'd like a couple of buttons when viewing New Posts to mark a post as read or to lock it as unread (until you mark it as read).

I'm using the db instead of cookies to keep track of what's read, and sometimes the list can get a bit long if there are posts I'd like to come back to, but not just now.

Ajax would be preferable, to save reloading the page.
