Why hasn't this been implemented yet?
This will be really nice and useful. Plus there will be a setting, where, if we tick a check box, all Mono Channel will by default have a Balance Pan-pot.
Then there will be another option with two check boxes and choosing one of the checkboxes will untick the other one.
Those options will be stereo channels by default will have either a Binaural Pan ( or another name is Dual Pan) or a Stereo Pan.
Also, at any time we will be able to cycle between Stereo Pan, Binaural Pan and Balance.
