Maybe a checkbox below the disc for toggling whether track times are shown in the textarea (that ideally would remember what state it was in last)?

Perhaps it could be a bit more clever, so that it automatically uses the old track times as long as the recording is the same. This could also be done when tracks (their underlying recordings) are reordered.

imo, if "Detect track durations" is not checked, it shouldn't "detect" them and so ignore any such times.

Right now, if "detect track durations" is turned off in the parser, it adds the durations as part of the titles instead, and loses all the track times. Still not good at all.
