Suggestion: Make planets on the empire tree appear in alphabetic order!

Good idea, though I'd suggest that the capital planet always be listed first and then alphabetical after that.

While they're at it, it would be nice if selecting one of the notifications in the bottom left (about war, attacks, etc) scrolled the empire tree to the planet it was referring to and highlighted it. Another tree bug that I'm not sure has been mentioned is that when you have one control group selected on the tree and you go to add units on another planet to that control group, the tree jumps back to the first units the moment you click on the ones to add- VERY frustrating.
