Support temporarily watching pages
Describe your suggestion
MediaWiki 1.35 introduced a new function, watchlist expiry, allowing you to temporarily add a page to your watchlist. This was recently rolled out onto WMF wikis.
Settings
Add a setting that allows you to change how long RedWarn watches a page for. Mockup below:
Context
Twinkle supports this option, and so do some other tools. Adding an option in preferences to change the watchlist expiry time will reduce watchlist clog, and remove irrelevant pages the user is no longer interested in.
