The Editor Comment block allows you to enter comments that show only in edit mode. For use by site developers who want to leave notes/comments for those editing a page in the future.
Use this block as you would use code comments during development:
To leave 'notes to self' To help teams communicate about what has been done and why As documentation Leave the comments on a site permanently Or uninstall when the site goes live and all comments simply disappear!
