I started a FAQ page a couple of months ago when I started porting my old VR code to XR / XR Input Toolkit, to keep track of all the undocumented items, and tips and tricks I was seeing on the forums and elsewhere.
I’ve got to the point where I know Unity’s code well enough that I don’t really use the FAQ any more - I know everything in there by heart - but I wondered if it’s useful to you, and if there’s any questions you think are missing that should go in it too?
