Cleaning up XLights

[K-State Fan]

Trying to clean up my xLights layout settings.  I had added items over the years and it seems like a mess.

Current setup is three FPP and three falcon controllers.  Two of the falcon controllers have LOR controllers hooked up on the serial output. How do I set the controller output for that?

I also have a a polyline drawn that is 3 separate strings that are on two different controllers.  How is the best way to clean that up?
