One of the things I like in GC3 is how the ships move in the battles: they aren't limited to 2 dimensions, like in Stardrive 2. They can move in all directions, including up and down. HOWEVER, the camera is limited. I've been through several situations in which theres a ship above your camera level, and you wouldn't be able to see it, because your camera won't allow. The only way click and hold the mouse scroll so that you can see the battle from "below".

Thankfully, this can be easily fixed by allowing the camera to be zoomed out more or to enable it to move up and down. Simple as that.
