and less of a hassle:
I don't whether the devs will ever work on GCII again, but here are two things I would like
1. When you punch the colony button, bottom left, it should show what type of planet it is: normal, toxic, high grav, etc. This would be particularly helpful for the unowned list when you want to colonize.
2. When you capture a planet and get tech, you should be able to refuse it or have it not automatically go into effect for all of your planets. Sometimes getting a tech is a tremendous economic curse and can drive you into the red unless you go planet by planet deleting improvements (like high level factories that you cannot afford). I think you can turn this off per planet in TA, but I want it simple for all of my planets.
