jesus2099 / mb. POWER VOTE

// ==UserScript==
// @name         mb. POWER VOTE
// @version      2024.4.11
// @description  musicbrainz.org: 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). Fast approve with edit notes. Prevent leaving voting page with unsaved changes. Add hyperlinks after inline looked up entity green fields.
