When working with track listings, it can be useful to grab the plaintext in order to use macros or text-processing tools (sed, grep) to alter the track title:
01 Aria - Don Quichotte - "Ein wahrer Held eilt schon ins Feld"
Don Quichotte auf der Hochzeit des Comacho: Szene I. Nr. 1 Aria "Ein wahrer Held eilt schon ins Feld" (Don Quichotte)
Some manual modification is still necessary, but automation certainly simplifies the process.
Currently this sort of modification can only be easily completed when adding a new release, because when the track parser is used, it resets track to recording associations (at least when I change text with the track parser, the modified tracks say 'select' on the recordings tab.)
It would be nice if the modified tracks could retain their existing relationships.
