Apologies if I'm missing something, but shouldn't sources of culture points be visible somewhere? There's a mouseover for control points but I have yet to find one for culture points.

Also, on taxes, it would be nice to have some more granularity on the settings. You've got your core worlds up to 96% approval and you think it's time to maybe squeeze a bit more coin out of your people, and then you jump from 33% to 67% tax and world approvals drop to 60-80%. However, a 50% tax might be just right. Anyway, I'm not sure why this can't be set to the integer like in GC3 (or another game?). Even a few more choices would be nice.

Also, 96% approval seems to be a limit, until later when you can eke out 97% on a few worlds. Not a big problem for me, but it seems curious.

Cheers,
