I wonder if it’s possible to give users and groups permissions to templates in a specific folder.
When logging in as a user “Templates” menu isn’t available and I can’t figure out how to give access to it via a group.
Using Features you can give the User/User Group access to the Templates page. Use the row menu for a User/User Group and select Features. Expand Layout Design from the Content tab to enable the required actions for Templates:
You can then save selected Templates to Folders and set Share options for the appropriate interaction level to View, Edit, Delete for the User/User Group.
