I thought the UI for MSFS in VR was awful.
Though I think some of that may be because of the game controller I use. It's an Astro C40, which due to driver issues, can't decide to tell Windows if it's an XBox 360 controller or an actual Astro C40. If it identifies as a C40, then games don't know what it is and don't have any default bindings and I have to configure it all, and with a game like MSFS 2020, there's a lot to bind. But also, lately, I've been having an issue with it deciding that the controller only has two buttons and nothing else, not even analog sticks.
But I digress...
I think MSFS in VR would be a LOT better if it gets support for controller-free hand tracking, like the Leap Motion. I'd still use a game controller for the main inputs (Flight stick, brakes, rudder, probably throttle as well), but I'd love to be able to just reach and flip light switches, turn dials, etc.
