Good point. ;) Temporal edits in the middle of audio data (cut,
insert) will be inefficient. But again, IMHO this is another level
of audio editing. If you start moving drum hits around, maybe it's
time to do a re-take... :) If I need to do stuff like this, I use
a sequencer (MIDI, tracker, audio, ...) and then export the data
to the multitrack environment.

Hmm, I'd record the punched material into a separate file (hey,
diskspace is cheap). Replacing previously recorded material makes
sense with traditional recording gear, but in a computer-based
recording setup, I don't think it's necessary. And this makes undoing
easy.
