going through rushes in real time is slow and running at 2X is unintelligible, esp for documentary material. LIke FCP7, there should be a 1.5 play speed which would cut hours from previewing material.
Some audio effects have a bypass button, but all effects should be easily toggled on and off, so you can leave them in place and compare with and without. Shouldn't have to save the effect to a bin to make that possible.
Also, as noted elsewhere, the system shouldn't stop playing when you toggle bypass in an audio effect! You need to hear both states while listening continuously. most DAWs can do this, why not MC??
