Panning reverse

[DotNet-ImaginationSquare]

This will help miles in mixing, as imple button next to the panning slider (or any slider but mainly panning) that allows you to swap it around, e.g. if it was set to .5 to the right it would become .5 to the left. (that or PLEASE add a numeric input system in the advanced that is NOT console to just give a specific value for those sliders PLEASE)

Thanks for reading <3
