Full VR Interface

Just give Blender the tool menu from Gravity Sketch or Kodon.

Every menu, panel, option, should be accessible through an organized panel when pressing the menu button. It can even have holding a key and using the joystick to access 4 types of panels.

Node editor could be pinned, grabable and resizeable. Same for render and compositing windows.

In sculpt mode and texture paint mode the pressure can be controlled by the trigger pressure or by the proximity from the tool like spray cans.

$50 would be a good price to buy such addon if it is decent enough.
