Feature Description

Hi, having an power mode UI would be great

I did these to archive the ui experience with notifications:

`# Power Management

• bind = CTRL, 1, exec, powerprofilesctl set power-save; cpupower frequency-set -g powersave; notify-send "Power Mode: Power Save" --icon=
• bind = CTRL, 2, exec, powerprofilesctl set balanced; cpupower frequency-set -g schedutil; notify-send "Power Mode: Balanced" --icon=
• bind = CTRL, 3, exec, powerprofilesctl set performance; cpupower frequency-set -g performance; notify-send "Power Mode: Performance" --icon=`

Also with the brightness controls.

• `bind = , XF86MonBrightnessUp, exec, brightnessctl -q s +10% # Increase brightness by 10%

• bind = , XF86MonBrightnessDown, exec, brightnessctl -q s 10%- # Reduce brightness by 10%`

config has an ui for that in the control center but it would be great if there was an ui just like volume ui after i press the brigness Up/Down keybind.
