For me so far while I prefer Insane /rare/rare maps to be hug but not too many planets (with lots of space between folks)
The 'planets' I can manage fairly ok and while I could list improvements, I can live with what is.
Now Starbases I find very annoying.
Changes I would like to see:
1) Starbase 'build alll' Probably only an option after 'ring' has been selected, but after that a check box, that if there are free constructors at base, it build anything available. Sure it might not build the order of preference I want, but a lot more manageable then clicking 20-30 times, at time to 'improve' a new starbase.
(or worse yet, having to click on 80+ right arrows to scroll through starbases) then click on an improvement for each one when new tech becomes available).
So far starbase management is the single biggest, 'aggravation' to my carpal tunnel, so much so that I have about 4-5 mouse automation scripts designed to ' do everything for me, so I CAN play
2) An expanded on the above, I would love to see instead of a 'build anything' a 'focus' so I could tell a starbase, to build, Defense, Offense, 'Production', or 'Misc' (or perhaps rate the 4 in order of preference). Then if a constructor was available (and a build option was available) it built based on preference.
3) REALLY need more keyboard control versus mouse. (**** REALLLY would love this one *****)
Something as simple as being able to right/left arrow (or page up/down) to scroll through planets / starbases instead of using mouse to click the arrows at top of screen would help a lot with Repetitive Motion Syndrome.
