At the bottom of the ManyCam screen is a row where you set up items which don’t seem to be named anywhere in the docs, I guess you could call them “scenes” or “sources”. You can “TRANS” or “CUT” between them. How do I delete one of these? I don’t want to “Clear Layer” it, I want to delete it to the full extent that it no longer appears with a numeric tag, just the + as seen in the other nonexistent items. I’ve attached a screenshot of this area for clarity. For example I want to delete “FRAME 3” - how?
