Separate Create items permission from Create templates permission
Currently, if I want a copywriter to be able to create items, I also have to grant them Create template permission.
The Roles & Permissions UI treats these as separate permissions but in practice you must always enable create templates with create items, otherwise users get an error when they attempt to create items.
Users who create and edit content are not always the same users who create and manage data models/templates/structures. These permissions should function independently.
