Feature requests: what should the next launcher update have?

We read every idea here. To keep this thread useful:

- One idea per reply, so others can vote on it.
- Say why you need it, not only what it is. ("I play on 3 servers and want my settings per server" is better than "profiles plz".)
- Press Helpful on ideas you want too. We look at the most helpful ones first.
- Before you post, check that someone hasn't asked for it already.

Bugs and crashes belong in their own thread, not here.
