I have tried twitter app after twitter app and they all have features I love (and are all missing a few features i want desperately), so here is my ideal. 1. The big and easy to read, full scrolling widget of my native twitter app on my HTC EVO. 2. A reply and tweet button or (even better) always open/easy to hide text area for posting tweets. (Meaning I don't have to hit the menu button to open it). 3. The ability to filter the tweets in my feed by user. I follow some people like family, or news feeds that are fine when I am sitting at my PC, but on the go, I would like to narrow it down to those I really care to see on a regular basis. 4. Retweet w/comment. 5. Automatic link shortening. I am sure there are a few small details I could add, but if I had a twitter app that had all of this, I would never stray.
