Describe the solution you'd like
Add support for OBS Canvases once that functionality is available in a release of OBS+Websocket
Additional context
Currently it's not possible to access additional canvases (eg. Aitum Vertical) from OBS Websocket or Firebot. A proposed PR is open on the OBS side which would allow accessing scenes and sources in additional canvases. Once this is out, Firebot should add support for additional canvases as well.
