1) Conversation threads similar to how Seesmic Web displays them would be awesome -


2) Reply-To-All

3) Threaded Reply (related to (1)) - Right now, Reply appears to be nothing more than including the @handle in the tweet without really "replying" and acts more like a mention which causes threads to break. A conversation going back and forth between 2 clients that support threads can be broken by a 3rd person jumping in on TweeGo ATM.

These are what I would consider important (not in order)... DM/Twitpic/etc. aren't incredibly important to me, sure they'd be nice, but if TweeGo didn't have DM/Twitpic I'd still use it!!! The 3 I mentioned are a different story however!!!

Keep up the good work!!! TweeGo looks to be THE Twitter client for N900 soon!!!
