The A/B button on the plug ins. Cubase has had it for years. Its so helpful to open a plugin, try a setting and then click the B button and try another setting. Then switch back and forth to see which one sounds the best.
In Montage include the same button that is in the Wave Editor for swapping channels. Going to a plug in folder grabbing it opening it up and click for the channels to swap takes too many steps. Have the icon button right in the center of Montage like the Wave editor so one click would hande the task would be great.
Thanks for your suggestions
