I have just briefly used some of the earlier betas and then went back to the last
official release of DA.

My question is that when you hit the bottom left side colony button, can you sort the unowned by the type of planet -- normal, radioactive, aquative, etc.?

I spend a lot of time when picking a planet to colonize, poking on the icon to see what kind of planet it is.

Another way:
Instead of a sort, all planet could come with an icon showing what type they are.
