** Problem Definition **
Many get confused by the two sliders.
One 'You Tuber' insists that moving the empty slider one position left should empty to that level, yet still be able to recieve input.
That does not work. It disables input.
Currently only one slider can be used. Either the full (green) or the empty (red).
** Resolution **
I think there should be one slider only. Default the slider to the center. Let us move it to keep full, keep empty or somewhere in between. The new 'Simplified' Logic would fill to the slider position and empty if to the right of that amount.
