Using VR for a while now and it's definitely let me appreciate using motions and gestures to interact with our workspaces, but it's definitely something that isn't accessible by the major public.
A little addition I think would be a good idea is to cut out the task bar all together and give more use to the mouse wheel click. When working normally you can click your mouse wheel and while holding it drag up to access programs to boot up, drag down to view all active windows (going into a full screen mode similar to alt + tab), right to access a search function and finally left to access file explorer. Users could then these access path with top right perhaps leading to command line or a specific set of programs.
