Useful Drupal modules
Click on the module name for notes, comments, patches.
Recommendations (for and against) are my personal opinion only and may be out of date. Feel free to email with corrections/suggestions.
Why haven't you mentioned Drupal 9? I will be adding this, but as of August 2021, this site you are reading is the only Drupal site of mine I've been able to upgrade to D9, so although you can check D9 compatibility status of all modules (use upgrade_status, it's superb) I can't speak from personal experience about any of them.(1 modules in list)

If you only need a small amount of CSS, or want users to be able to directly edit it through the admin UI rather than creating a theme or module.
Caveat: doesn't work for admin themes (at least on D7)
