You know what would be cool?
Full-on supercruise autopilot. I mean, it's even realistic. If the technology were available, why would a pilot want to control every second of boring straight-line flight?
But I don't care much about realism. It would just be nice to flick on autopilot for a 200k Ls cruise and go do my laundry. Sure, I'm taking a risk if something engages me en route, but that's part of the point. It's taking a risk for a little convenience.
Also it would be neat if the auto-pilot had a "scenic route" mode that just flies you all around the system lol
