It was such an obvious missing feature. Though to be fair, implementing undo/redo functionality is often nontrivial.
However, there's still no way to save/export scenes, aside from simply copying your entire app data directory. I just have a basic layout with few tweaks so it's not the worst thing ever, but for any streamer with a complex setup and carefully adjusted filters, moving to a new computer or whatever must be an enormous pain point.
Exporting and saving scenes can be done with export scene collection. It’s kind of clunky in terms of workflow but I’ve had success exporting/importing scenes across computers.
You can export your entire scene collection to a json file and import it on another computer.
If you keep all of your media and such in the same folder, then the new Missing Files dialog on startup will also auto detect every source after you point one to the new location.
