@christianaschoff The title can also be too long, but it is better handled in the UI. Except in the actual list view: https://lokalkauf-security-testing.web.app/bookmarks-public/8gxyRDvCYi1WzBUWfxZ7

UI is now limited to certain input sizes for the fields that is displayed while typing - like twitter does
