Permission favorites allow you to save a specified set of permissions. This is most helpful if you add permissions outside of the default permissions assigned to the user role.
Admin users can find the permissions favorite on the permissions tab, it is the star in the bottom left.
A batch action is also available that allows assignment of a permission to multiple users at the same time. Click the checkbox(es) to the left of the users you want to grant permission to, then click the drop down at the top of the checkbox column and choose Apply Permission Favorite, then the specific favorite you would like to apply.
