That sounds very promising. I remember reading that the devs like the terminal messages since its helps with debugging. Not sure they are interested in making anything like this official but also said go nuts for ur own machine.
I do think that the retropie needs sometype of variable switch that changes the retropie from development mode to a production mode that looks clean, polished and awesome!
It would be great the efforts of experiments get used officially. If not do u mind sharing on here if u dont hear back?
