Author features

What authors see. Each row is off until you pass its key (or, for Issues, install the optional quality package). The editor with only container still edits; it does not persist, comment, or send.

Provider methods run in the browser. Hide a control with false; enforce the same rule on your server. See Connect your backend.

No provider. Configure on init() or in template settings.

Issues is an optional peer: skip the package and the tab never downloads.
