Unknown regions
Would it be possible to have some regions we do not have a map for? We'd have a map of the known space and beyond that... we'd need to explore.
One of the letdowns, in SC2, was when I entered Quasispace and discovered that I had all the points available on a map. I'd never been there, for crying out loud. Let me wander around a bit, find my bearings and discover things!
Personally, I'd like it if, when stumbling on a region of space that hasn't been charted before, that we could see the larger/brighter stars but not necessarily less-visible stars like a brown dwarf, for example.
We could have wormholes that take us off the map.
Just like Vela was hidden, but doing this on a more routine basis, using in-game mechanisms.
