It would be very nice and more immersive if Dash could be placed in the scene of the application/game instead of being painted over the scene.
Use case:
A pinned webpage showing runes for OrbusVR's Runemage (that aren't recorded in the player's journal) is pinned in Dash so the player can practice tracing the runes with the in-game wand.
Currently, all in-game objects (hands and wand included) disappear behind the pinned window regardless of its apparent placement. Inserting the pinned window into the actual scene of the game would solve this and prevent pinned windows from constantly breaking immersion.
I don't know if this is possible with the current flow of scene rendering without creating an API for the game to interface with Dash features (rather than Dash injecting objects into the game).
