You cannot see on the fly if your planets are overpopulated in the planet report panel.You should not have to go into each system to see this..A green number for growing and red for overpopulated?
The strategic map does not show or have options to show.starbases,defences,shipyards.This adds lot fiddling about clicking everything.
Some sort of rally point system is needed too.Automated transports moving overpopulated planets would also help.
I find lacking these basic things add lots of clicking and wasting time.The game is pretty streamlined so the UI really should not be making me click more than GC3.
