I don't know if this will get seen at all, but here goes.
This app is my favorite Twitter app for iPad that I've tried. However, there are a few things that keep it from being a complete gem for me. I'm hoping that Andy is working on these as I write.
1. The lists don't remember where I left off. Simply put, it always scrolls me to the top/most recent post in the list, and it should not.
2. Adding people to a list is bizarre. From the lists it is okay, but if you tap on a tweet that has someone you want to add, then tap on their username, then tap on lists, you are now viewing a bunch of unrelated tweets. At the top right of the pane, it says "username Lists." Tap on that, and you get list info about them with a "+" where you can see your lists and add them to it. A few too many taps, methinks.
3. I would like a way to sort my lists. I know Twitter doesn't do this, but who cares. Ideally I could resort my lists into any order I want, the next best thing would be an option to sort them alphabetically. Then I could rename them if that's the way I need to get them in a useful order for me.
Keep up the great work!
