One feature that I found myself looking for is the ability to search within your own favorites list.  Alternatively (or maybe even better, in addition), it would be awesome to categorize or tag your favorites.  Then when looking in your favorites, you can just choose the tag(s) you're looking for (like gmail does it).  Either way, being able to organize your favorites would be helpful.  As I'm thinking about it, it would probably be useful to (optionally) see your personal notes when looking at the favorites summary (so you don't have to go into each profile to read them if you keep them short).

On a related note, it would be great to be able to search within your search results.  I find myself creating a bunch of different search variations because you can't do it.

Anyway, those are just some ideas to make searching easier to organize.  Any thoughts from the gallery or TER organizers?
