If I already have discord open on desktop then when I load into vr home it should already be pinned where it last was pinned. Going further you should be able to switch between arrangements. Where windows are pinned in one vr experience might not be good for another. So I should be able to pull up dash and hit a button on the carousel just like the monitor button, which would then show my bookmarked arrangements. Selecting this button should automatically pull up all the windows of that bookmark. If it's not possible to auto launch and programs for the last of windows at least have it fetch currently loaded windows that match the list.
