Yeah Dave’s such a nice guy to chat to as well. I love his work, VSR has become essential and an enabler for VR pilots to fly in Vatsim. He’s constantly improving this app with useful features and quality of life updates. Big fan of it.
So the FSDesktop app is still in development. There’s a link I’ll paste below with a bit of information and also a channel of the Fskneeboard discord. I think Chris, the developer is trying to be careful with messaging about what will and won’t be possible in the initial release. Building this kind of bridge between msfs and apps running in the OS isn’t trivial and there will be restrictions - I believe it might be mouse clicks only initially but then maybe a virtual keyboard etc (which fskneeboard has so maybe not too difficult to port across).
