[FEATURE REQUEST] Option to add multiple sliders for brightness and volume control #65
Description
Describe the feature
Currently KDE Control Station has two sliders - volume for the default audio output device, and the brightness for the primary display. To access the volume levels for other audio output/input devices and the brightness for any additional displays, you need to click on the slider area and open the system widget instead.
It would be really useful to have the ability to select more devices to be controlled via the sliders. Use cases for example:
- adding a secondary audio output volume control for users with two sources;
- easy access to microphone level;
- additional brightness slider for a secondary display;
Additional context
Came up with this request because I have two displays and I change the brightness on them quite often. It does not make much sense to change it only on one display and leave the other as is, so instead of using the slider displayed in Control Center I have to call the system widget that can control them both.
Mockup of what I suggest:
