Search→Replace from @kellnerd mentionned SUPER TURBO is a yellow button below tracklist in release editor when you have enabled the TRACKLIST_TOOLS in this user script settings, found in the MusicBrainz Editing menu
It does support regular expressions if you put /
slashes around your search, as explained in the documentation
The documentation is found inside the prompt that appears when you click that yellow button.
This script only even has its own documentation, accessible through a HELP link in its settings panel. But I’m afraid it’s not really up to date.
The @chaban mentionned PLAIN TEXT TRACKLIST adds some links in the release page sidebar to copy text tracklist without launching the release editor.
As for the lack of documentation, it’s just that I am making public some scripts that I write for myself.
Sometimes I think I should not publish them (MASS ISRC, MERGE HELPOR 2 and MASS MERGE RECORDINGS in particular) as some editors are abusing them and that makes me loose HOURS of fix edits in my collection.
But many editors are making great things out of them, so it’s kind of a dilemma.
Barely having time to support those scripts themselves, I have no time to write documentations, sorry.
What you do, copy from source tracklist, modify it in text editor then paste in destination tracklist is already the solution.
I don’t know what else could be done.
The answers given were still not off topic I think because one of the scripts allows to copy source tracklist without going into the release editor (which might be a small gain, however). The other script allows you to use regular expression search replace when you just need to edit a single release (not copy from one to the other).
Hint about userscript documentations
By the way, here is a hint apparently you don’t know yet.
Userscript is usually explained in its // @description
line, near the top of its source code file.
