I've set up my lights so they're on during printing and off otherwise, which is what I prefer. However, when I'm doing things like changing the build plate or applying glue, I'd like to be able to quickly switch the lights on so I can see what I'm doing. Currently I have to go into the settings and turn off the "only on during printing" option.
It would be nice to have a button in the corner on the home screen to just turn the lights on or off, preferably available during prints as well! I'm not sure what the behavior should be when the printer performs an action that would change the lights, like starting a print. Perhaps the button could cycle through three options - on, off, and "as configured in settings".
