Small QoL Improvements

[Nadirah]

Just a few small QoL improvements:
The UI is already leagues ahead of other out-of-the-box MMO UIs I've seen, but these would just push it a little further.

And at the same time, leagues behind because there's no addon support.

Seriously. Addon support would fix just about all of your things listed there.

And friends list notification. I want to know when people on my friends list log in damn it.
