Community Wishlist Survey 2023/Notifications, Watchlists and Talk Pages/Watchlist edit - "check all" checkbox/Proposal

• Problem: When removing pages from Special:EditWatchlist you must manually check every page, even if you want to remove all (or almost).
• Proposed solution: Add checkbox "Check all" above list of pages for every space.
• Who would benefit: Everyone.
