pseudoprime:As long as we're making feature requests, how about an auto-detect based on the coordinates? I use a website for tracking my bike riding that, when I upload the GPS tracks, "guesses" which town I'm in. OK, it usually guesses wrong, but it never gets the state wrong.
I've found fairly often people posting the wrong state, especially when most of their waymarks are someplace else. I always feel like I'm being a little annoying when I e-mail them to ask for a correction.
I asked about this on one of the IRC chats. They didn't do it because of the cost of their geocoding service...or something similar.
