It would be very useful to have a strategic map on the planet build screen. On larger maps with abundant planets you can easily forget where a planet is located in your empire and which role was assigned from a strategic point of view. Inner planets tend to have significantly different builds than outer frontier planets so easily seeing the location on the strategic map would be useful.
On that subject, being able to assign a ploanet to sponsor a shipyard straight from the planet build screen would be a nice touch for the same strategic reason.
Thanks
