Hi,
To make this amazing thing that is Reaper even more amazing, would be the addition of 360º video playback. This is a new and upcoming format that is expected to get a lot of traction over the coming years...
Could that be done? It would be similar playback functionality like this app, but now right in the Reaper timeline:

Maybe Cockos and Kolor can partner on this...
