In the govern screen we can see the current production/research/wealth in their respective columns. What I'd like is to be able to see is what the maximum values for each could be. In the early game this isn't a big deal but once the number of colonies grows it would be nice to decide at a glance which world i want to make my research/manufacturing capital etc.
For the galaxy minimap an option to see the area of effect of starbases (especially by type, ie. military/mining/culture/etc.)
The sidebar list of ships/starbases/notifications should allow for filtering (by type/size of ship, also if ships are in a fleet it should show the fleet and allow the fleet to be expanded into a list of ships with a click). notifications should move red/yellow to the top of the list(or have some way to sort/filter)
Ultimatums...allow you to threaten and be threatened with various demands (hand over a starbase or else)
The reverse of the above: once war has started (gimme planet X and I'll call off my fleets)
and correct the spelling of "steller wake" (military starbase upgrade) it gets anoying to see a typo repeated over and over when i'm building up an imperial highway system
