I think you should be able to Filter through Planets by the Legion that occupies it.

I personally have found myself looking through dozens upon dozens of planets looking to see if any are owned by a specific Legion when I am asked if I have one by whatever Legion. It gets tedious after the first time you do it. It would be a great addition in my opinion.

Suggested about every week, It may also be hard to implement. Still +1

Ah, yeah. I was told that by someone who's in the Legion that I'm currently over in once I posted the link. Haha. Apparently Dan said something about planning to implement it sometime but isn't sure when.
