Allow vertical controls on left and right side of the screen

Feature description:

I’d like to have an option to display an item/control on the left and right edge of the screen

Problem solved:

On unfolded pixel fold and tablet view, there’s a lot of screen space that could be displaying the cover art but is lost because of control items. It would be nice to maximize the space a bit more

Brought benefits:

I think it would just look good and be a nice customization option for everyone, especially if other things could go on the sides. It would really expand the potential interface designs

Other application solutions:
