One thing that really makes colonization difficult is the change of the "planet status" from colonized to available if you move your ship out of a system. I would like the planet status to remain the same as the Last time I "saw" the system. However, this would probably take significant programming or large player files.

Another option would be to show that the "unseen" planet is colonized but without the designation of who owns it to avoid giving away information on conquests. That way I could plan my colonization without sending ships to planets that are already claimed.
