Mail Template Operating Unit

This module extends email templates (mail.template) with an Operating Unit field. When a user creates a new email template, the field is automatically filled with that user's default operating unit, so templates are usually assigned without extra effort.

The Operating Unit field appears on the Email Template form, right after the scheduled date, and also as a column in the Email Templates list. Both are only visible to users who belong to the multi operating unit group, so companies that do not use operating units are not affected.

A global security rule limits visibility of email templates: users can only see templates whose operating unit is empty or belongs to one of the operating units assigned to them. This rule applies to reading only; it does not restrict creating, editing or deleting templates.

The module touches the email template model and its form and list views, and depends on the operating unit and mail modules. No new menus, reports or scheduled actions are added.
