A lot of the time, I fight around the sun, seeing as its the entry point to my system, its the best spot to contain any invasion.
However, as the sun is in the middle..it has made movement and fighting in that system akward.
I suggest moving the sun beneath the plane somewhere to give us more fighting space...in addition ships use aaaaaaaaaages forming up for warp around the sun too...AI gets stuck there all the time.
Solve this easy imho by either reducing sun size or moving it out of combat zone.
