Bunch of other fandom annoyances: https://letsblock.it/filters/fandom-cleanup
Check out the uBlock Wiki! uBlock can do so much more than just block elements or network requests, you can use scriptlets to get rid of so many annoyances or the :style() operator to make sites look better and cleaner, without having to add a whole userscript manager. And if you auto delete cookies/localstorage for privacy reasons like me, you can still keep some individual site settings with the trusted-set-cookie or trusted-set-local-storage-item scriptlets. Also the :has-text() selector is really useful to filter out some annoying keywords in social media posts, it even supports regex!
