Make volume control bar (slider) always visible

Hi,
I’m using an old smartphone as Yatse remote which has faulty volume control hw buttons.
Would it be possible to have the volume control slider always visible on the remote.
I know I can control the volume with the graphical buttons on the remote, but it would be so much easier using an continuously visible slider on the screen.
Cheers,
Luc

Hi,
just got an idea to implement this with “minimal?” effort.
On the Remote screen you could get rid of the Mute button inbetween the V- and V+ button and replace that with the slider? You could still mute to touch the slider at minimum, (fine) adjust volume with the V- and V+ symbols. You also would always have a visual indication of the Volume set. The reason why I find a slider more convenient is that you can quickly change volume in big steps and keeping the possibility to fine (small steps) adjust.
Cheers,
