PC, background input

So since this is a windows 10 app its nice to just jump to windowed mode quickly, but I’d really love to see some sort of background input if possible (if the windows store allows it?) this way we could use our browser while still playing, so say you have a quick moment to rest, being able to quickly change a song on youtube or reply to someone on facebook etc etc. Obviously this would only really work with a controller since it would be a bit difficult to keep a keyboard as background input if typing else where.
