The only problem with save/load in faders is haptics. Touch screens can show dynamic content and work like a fader just fine.

(As opposed to a knob, which does not work right without the physical form.)

Once someone invents a display with programmable shape, there's your programmable true fader.

What about the iPod circle? That is basically a digital pot.

In fact that idea is used on a bunch of Bluetooth speakers including Harmon Kardon and Google Home to control volume.

iPod 'circles' are physical. They are resistance based just like pots. Nothing digital about them.

My point is it's the knob equivalent of a touchscreen fader.
