Critical

Could not edit MB without these:

mb. INLINE STUFF: musicbrainz.org release page: Inline recording names, comments, ISRC, PUID and AcoustID. Highlights duplicates in releases and edits.
MusicBrainz Copyable artist credits: In addition to copyable ACs, it lets you edit all tracks that have the same artist. Requires some caution though.

These make MB much easier to edit

mb. POWER VOTE 1.0: Adds some buttons to check all unvoted edits (Yes/No/Abs/None) at once in the edit search page. You can also collapse/expand (all) edits for clarity. A handy reset votes button is also available + Double click radio to vote single edit + range click with shift to vote a series of edits. , Hidden (collapsed) edits will never be voted (even if range click or shift+click force vote).
mb. FUNKEY ILLUSTRATED RECORDS 1.0: musicbrainz.org: CAA front cover art archive pictures/images (release groups and releases) Big illustrated discography and/or inline everywhere possible without cluttering the pages
mb. TAGGER LINKS NOW 2012.1106.2230: musicbrainz.org: Quickly show or update "TAGGER" links with desired port
MusicBrainz - Colourful edits 1.0: A script to add colour to the edit headers in the edit search results.

MusicBrainz - Batch-add composer/lyricist/librettist/arranger/orchestrator/publisher/part-of relationships 1.0: Create various relationships between an artist and the selected works or "part of" relationships between a main work and selected works from an artist's works list. Based on bitmap's 'Batch-add "performance of" relationships' userscript.
MusicBrainz Relate recordings to works from a release: the predecessor to the relationship editor, just does the works side of it. Has nicer date editing than the rel. editor.
MusicBrainz - Link work to recordings 1.0: MusicBrainz : Batch linking a work to recordings
MusicBrainz Fast cancel edits: Makes canceling edits much less painful, no need to go to a new page and enter a comment for each one.

Extra MusicBrainz/AcoustID integration 1.0: Display additional AcoustID data on MusicBrainz mostly icons on tracks which have acoustIDs. Would be better if it did this anywhere a recording appeared, and maybe indicated how many acoustIDs there were.
