Hmm… There’s supposed to be a separate search field for the forum on the right side underneath Blog Search. But it must have been removed during a WordPress update or something. I’ll look to see if I can get it back.
I’ve been thinking about adding RTF support to the Notes field. It’s just a bit tricky due to cross platform issues between Mac and iOS. I know it’s possible, it’s just a bit more work to do to support cross platform. Maybe iOS 7 will make it easier.
