We use our GLD in a house of prayer that has people coming and going every hour of the day and night, 7 days a week. Lots of people use it and sometimes forget to turn of speaker amps, stage equipment, etc.
It’d be great to have the ability to add a custom message that pops up before or after the confirm shutdown dialog that the user must select “OK” on before continuing. I’d set it to say something like “Please turn off all stage equipment!” It’d be a great reminder that would be more effective than taping a piece of paper to the board. People get used to that and ignore it.
