This is not how userscripts should be done. But I didn't expect that thing, which was started 6 month ago as simple function tool, will became a huge handyman (tbh, 20 small scripts is even worse). About 80% of everything here probably most of us want to see on Derpibooru without userscripts.

If tag expression was edited manually (not watch/unwatch) or checked "As watchlist", all components will be checked for actual aliases and existence. For stability reasons do not manually edit more than 1 tag at once.
