Add an option in the favorites menu in the start bar to remove entries directly

There is no option to remove folders that you have added to your favorites in the favorites menu. You have to visit each folder manually and remove it from the favorites in the context menu. If you work a lot with favorites, this is very annoying.

You can use dconf-editor

path: /org/x/apps/favorites/list

Make a backup before editing
gsettings get org.x.apps.favorites list > favs.lst

Ok, thanks for the tip, but that's quite a cumbersome method.
