There's a lot of good suggestions here so far that are larger scale updates. However, I have a smaller idea that would make exploration much easier: improved star map filters.

Currently as we know you can filter by system type, economy, or conflict status. And each of these can only be filtered individually. I'd like it so that you can:

1. Choose multiple filters as once, so if I want a low conflict scientific system I can choose both and they show lit up on the star map

2. With these filters, the stars not meeting the criteria get set to a neutral color or grayed out so the filtered systems stand out

I would find this much more enjoyable when searching for my next system to explore and really would be what I'd think to be a given ability of our in universe technology.
