Installed it to my N810 and here are some areas of improvement (sorry if they have been mentioned);

1) I'd love to see the avatars and not just the twitter names

2) Some texts in the timeline goes past the right edge of the screen and does not seem to wrap correctly

3) Nothing happens when selecting direct messages, mentions or search.

4) Could you add a 'retweet' option that takes advantage of the now built-in retweeting function?

5) I'd love kinetic scrolling on the N810 platform as well

6) I would much prefer that instead of a full date and time stamp in the tweets that it would say 'Posted 4 mins ago', etc.

7) Auto-refresh of the timeline would be great

8) A better looking UI

9) When on the Friends/Contacts list it would be nice to be able to click the name of a contact and then see all his/hers tweets

Like the contact management options a lot!
