We are at a nice place with that mostly, but there's still a lot of room for improvement.
Ability to control as much functionality as possible from a joystick with a hat switch and buttons without contorting the UI into weird yoga positions like E:D does.
HUD is a nice basis. There's room for added functionality
- There could be proper comms (see above - non-combat gameplay)
- HUD for external docking
Flight UX is quite nice with the new flight computer. There's room for a bit of polish, but it's really nice overall.
Station screens could benefit from some facelift and UX improvement
Maps even more so (see also flight planning points)
Interactive cockpits for more immersive gameplay. But optional, one should be able to play the game with only a HUD as well.
