Specifically, this screenshot shows a customized menu option, sim (On, Off) and Sim (On, Off), that does not appear on the factory default pulldown menu.
What is the source file that includes the text parameter "sim (On, Off)"?
I know GL web interface is generally compressed .js but that text string "sim (On, Off)" is custom - and it doesn't appear magically.
My objective is to modify the text string "sim (On, Off)" with my own text, let's say "Bob (On, Off)", for example.
Try to check packages. This option could appear after installing blue-merle package. If it was installed, then maybe value hidden somewhere in package files.
