After looking through this list, I think the most useful feature is definitely "display search results in a tabbed view" - mostly because I like tabbed things. Aside from that, it'll be nice to have the ability to delete those "mistake tweets" and check out your tweet count directly from the mobile app.
What's in this version:
- Displays search results in a tabbed view
- Add and remove saved searches from universal search suggestions
- SSL used for network requests
- Font size setting
- Tapping on a map in detail view searches nearby Tweets
- Launch links directly from a message
- Ability to delete messages
- Added Tweet count to user profile
- Improved avatar loading
- Improved the way data is cleared to conserve more space
- Fixed a bug where music skips when refreshing, etc.
- Many other improvements and bug fixes
