I don't necessarily want easier or faster, though some little tweaks here and there would make things slightly less onerous - ADS to ping automatically, if enabled; DSS to be a little more informative; better system map - maybe an orrery etc.
What I really would like, however, is for exploration to be more interesting. I want to see more range in colour, size, orbital parameters and terrain of planets and moons. I want to see black holes/stars with accretion disks. I want to see comets, rogue asteroids, collisions and breakups, variable stars, supernova (either during or not long after the event). I want atmospheric flight, and landing on lifeless worlds with atmospheres - I think landing on habitable worlds is going to be a very long way off yet. I want to encounter strange and mysterious artefacts, the remains of long-forgotten civilisations - unrelated to the Thargoid/Guardian storylines - which won't lead to anything (other than maybe a little reward and your name on the discovery), but are simply things to search for and take selfies near.
In summary, I want more reasons to get out of my space-hammock every morning, change out of my space-pyjamas, and eat my space-toast looking forward to the new and unusual things I will (not "might" but "will") see today.
