+1, this has been suggested many times. This would be useful as at the moment the free warp can’t be used over live instruments that contain multiple mics such as drums, stereo pairs on guitars and real piano etc… due to phasing.
Chopping the audio isn’t always optimal, especially for instruments.
Also would be useful for putting backing vocals/harmonies in time that are in time with themselves but out of time with the music if the singer doesn’t have a good sense of timing. This seems to be needed a lot of the time when I do official remixes and want to add more swing to the track.
