Sometimes it is useful having some folders where everyone, both local and network users, can act with full control.
Finder interfaces sometimes fails, in any case this can be done by using Terminal or several utilities… by the way this small droplet does this and only this.
Drag one or more folders on the droplet and all users will gather full control on folders and their contents.
Droplet acts on file permissions, then further content modification could require a new droplet play to re-set permissive privileges.
