Greasy Fork

- Added support for new/edit work pages; can choose whether to simplify the dropdown on the filter; can select default language (different from filter language)
- Better regex, cover more pages (hopefully all pages with filters now)
- General code cleanup
- Added error logging: browser console alerts for errors in user settings (e.g. autofill on but no default language selected, invalid language codes)

More @exclude fixes. Legibility + now works with collections and the base .org/search page

Fixed bug in regex monster of an exclude line

Added button to add/remove language filters from the search box; green button to indicate when language filter is on
Cleaned and simplified code
CSS for button

(GM_addstyles probably not compatible with greasemonkey. tbc)
