you are right, I would probably prefer NOT to see the gds numbers all the time and the less is more approach to visual clutter is usually best, so ideally the gds numbers would be present when needed - turned on/off via scripting. I was hoping there was a built in option to add the gds numbers as opposed to a custom SKILL approach. Being a novice programmer, everything seems convoluted and a bother. But these accomplishments are very satisfying once reached, so I'm not deterred, I am rather encouraged that there is a potential solution!
I will see if I can get a function to re-load the techfile with or without a gds concatenated layer abbreviation, and use it to toggle the visibility of the gds number in the LSW.
Thank you both very much.
