Recently active topics in Twitter tagged with friends

It would be nice to be able to organize followers by most recent to start following you. I'd also like to know who has notifications turned on for me.

I've got a few ideas for how the reply options can be optimized:

Per User Options.
Right now, you have one option, for everyone you follow: @replies just to you, all @replies to people you're following, and all @replies. While this is a nice feature, it'd be better if there were also per user settings. For example, let's say I'm interested in all @replies from everyone I'm following except @user1. Maybe they respond to every single tweet, even if its just for "thanks," and I don't really care about all of those. They reply with content I'm not interested in. I'd be amazing if there were options on a per-user basis for how replies should be handled.

No @replies to Protected Updates That I Don't Have Access To.
Let's say @user1 replies to @user2, and @user2 is a protected user that I do not have access to (I don't have permissions to access his/her tweets). That's just frustrating - I can't see what @user1 is responding to, which therefore makes that tweet from @user1 completely irrelevant to me - meaning I don't have a point to seeing it. I'd love to see an option in the reply settings to be able to block out replies to protected users that I lack access to.

Just thought I'd throw those two thoughts out there.

My idea is for a stripped down followers API which would just return the nickname and id of all followers (fields "name" and "id" in the current JSON output).

I've built a followers "history" tool (lets me track the addition/subtraction of followers through time). I'm finding I'm getting back the latest status for each follower and the follower's bio information even if I make a "lite" request (appending "lite=true" to the request).

Until oAuth (or something else) is deployed, returning all followers in such a request would eliminate additional API requests.
