'Shortcuts' on the main screen menu bar - one or two free spaces where you can assign regular tasks or actions - for example, open the glove box, cycle between chill/normal/sport acceleration modes, open all windows, etc.
I'd also like to see improvements to the 'energy' tool - although not exactly sure what...
Driving data stored/overlayed on saved dashcam footage (speed, location, etc)
Improved summon (Though this is more-so UK regs related!)
Improved windscreen wiper sensitivity
Stop the headlight levelling bug (Mine default to as high as possible half the time!)
Energy usage history - and journey/trip logging - location, speed, etc
Speed cameras on the maps!
