[request] do not decrease brightness of the display when switching power profile

[daniele821]

Currently, whenever changing the power profile to balanced or battery, the brightness of the display gets decreased. That's annoying when I rely on switching the power profile every time i unplug my computer (which doesn't last much on battery).

Can the power profile not change the brightness of the display? Otherwise can it be added in the settings a toggle for that?

Or even better in my opinion, would be to make it possible in the settings (once there will be a brightness section in the settings) to choose at what battery threeshold to change the brightness, if one wants to.

If this change cannot be made, could it be provided at the very least as a flag option in the system76-power cli?

Thanks
