In our Mantis installation, the user with the Manager access level is not authorized to import issues, but the Import Issues tab is visible on the Manage page. Is there a way to hide this Tab from users with the Manager Access level? An error message is displayed when the Manager tries to access the Import Issue Tab. However, it is better if the Tab is only visible to the user authorized to use it, as they did in the Manage Plugin and Manage Custom Field Tab.
