I think Distant Worlds has a colonization planner which allows you to see all planets lised on one screen where you can filter and search them in different ways to help work out your colonization strategy.  I find in ES2 I'm jumping around alot between systems when I'm trying to work out which new colonization tech I need, and it would make things a lot easier to have all the planets listed in the same place so I can see at a glance how many available snow, or gas or whatever planets are available.

In small galaxies looking for new potential colonies is not much of a problem, but since I like large and huge galaxies I do run into the hassle of keeping track of all good planets to settle. I too would like to see a colonization planner implemented.

As a fan of gigantic galaxies, i could totally use this!

Not sure if there's an idea of this. People asked this feature since EA.

If you make an idea PM me to vote. Just in cade you don't my +1 to this thread
