Direct Offline Process: Master Bypass (no processing/), Process History, and Dry/Wet Mix

Master Bypass,
compares the total sum of process (the final process in the chain) with the original file, no processing delay - it just flips between the original file pre process, and the final process file.

Process History,
Instead of just having bypass, I’d like to see a DOP-RightZone process history, in which all files have been retained and can be switched to, or even dragged and dopped onto a track.

Dry/Wet Mix,
Would allow one to blend in the original file, great for sound design.
