Quick Interface question...

[Alneyan]

I was also searching for that kind of option, but I could only think of a strange fix. I am adding a "Colony Finished" satellite when the colony is completed, and the queue is set on hold. That way, I can see in the Construction Queue window what are the colonies where I can still build facilities.

You could also add other labels so that you will remember that planet will need an upgrade to its [insert a name here] facility, and so on.

It is not really convenient, but I find it to be much easier to manage than having to remember which planets are completely filled up. Hope that helps!
