So this year I'll have 22x E682 controllers up, and spanning them with ~130 Universes - thus 130 xLights Outputs.
xLights 'bit' me a bit last year with 60-ish universes because I used straight xLights 0 based channel numbering (i.e. Offset from 'None'). So when I had to add one more flood light to the end of a string at the top of the list, it shifted down all my channels numbers for all other outputs, and all my sequences stopped working.
Not going to do that again...

So this year I'd like to switch to use some sort of relative addressing.
Ideally it would be relative to something I can specify myself on an Output (and can swap around) - like the 'Description' field, but there isn't an option to bind a Model to an Output Description.
My options are:
* Relative to output #:
-> Not crazy about this, since it means I can't ever delete an output - it will change the output numbers for everything below it.
* Relative to universe:
-> This is really IP Address + Universe. It's not unworkable, but it means using a separate excel spreadsheet to keep track of my controllers. No way I can't remember 130 Universes by number.
* Start/End of Model:
-> Trying to get my head around how this would work. It seems if I can create fake elements to exactly track the controllers it would work? Going back and forth on whether that is actually useful.
Any best practice here that someone can recommend?
