Let's create a definitive thread listing functionalities . @Twitter should have but doesn't. I'll start.

- Your entire Following/Follower lists should load at once so you can instantly scroll to the bottom rather than it taking literally hours

- We should be able to sort our Following/Follower lists by several criteria: Follower/Follower count, alphabetical, last tweet (oldest/newest), join date, tweet count

- We should be able to do free-text searches our Following/Follower lists

- We should be able to see a list of accounts that have recently unfollowed us

- We should be able to see a list of people we follow who do not follow us back

- We should be able to see a list of our most (and least) engaged followers

- We should be able to turn retweets on and off all at once, rather than having to do it manually one account at a time
