Well, I'm not a programmer, so I can't say how easy or hard this would be, but it doesn't seem to be a major change so I'd like to request it:

Planets on the colony list and the planet list do not currently tell you what kind of extreme world they are. You have to guess based on the color or memory (or if you wrote it down) which colonies are extreme worlds and which aren't.

What I'm requesting is possibly a new tab, or at least an indicator graphic on the colony management page as well as on the planet list which would represent which planet has which extreme environment. The graphics already exist, so it wouldn't need to be a new set of images. The best scenerio would be a tab that would organize the planets by extreme environment.

This isn't a huge deal, but it is annoying trying to decide in which order I should research extreme colonizations when I've got 30 planets around with a random set of extreme environments and no way to tally them other than writing then all down on a piece of paper
