[ HOU-2503 ] Quick preview button "before/after" modification for Lightmix

[creac]

Hi,
It could be very useful to add a quick preview button to lightmix to be able to swap between before/after adjustment very quick. Even a keyboard shortcut. "P" for quick preview.. similar to camera raw for example. Thanks.
