There is already a request for showing one workspace on multiple outputs (#1405), but I feel the ability to mirror outputs completely would be useful as well. What are your thoughts on this?
This will be addressed when wlroots is completed and integrated with sway.
Does this work now? I tried
output eDP-1 pos 0,0
output DP-1 pos 0,0
but that only mirrors the cursor not the workspace.
