still some 100% planets are not shown in the expansion planer (only >50% planets).

but great work otherwise [:)]

5. An option to hide planets that already have a Spaceport (or one in queue)

Further thinking: Hide/Show Planets should not be a dropdown menue but a Checkbox (since some Planets are equally "good" for some races we should be able to see more than one type of planet).

up untill 1.0.4.9 I got this on a regualr basis (every hour or so). But still I could continue to play, although I believe it killed the ship assignment AI.

simple soloution would be to make more filters for the colonization screen (like type of planet or distance or alien civ, etc.)

I do not think it wise to show all planets in that screen, less you want a cofee break every time you open the screen.
