So you support mouse input, but not a cursor...? Are you saying I have to use my head to point, and the mouse button to click?
Having to move your head to point kinda defeats the purpose of "mouse support" (and will probably give you neck problems).
Would be great if when moving the mouse, there was a virtual cursor (similar to the laser pointer you get with a vive wand).
*and also, as you mentioned, I noticed you need to click the window before any input is recognized. So you need an option in the settings to allow the app to take control of the mouse cursor, otherwise it's very easy to click outside the window, and lose window focus.
