For each toolbar in your application, the user should be able to choose whether or not to show that toolbar, and whether to show its contents as icons only, text only or both.
Allow the user to override the control center toolbar defaults for your particular application in the application's Preferences dialog. In particular, ensure that the user can:
If your application has a single toolbar, allow the user to turn it on or off with a View ▸ Toolbar check box menu item.
If your application has two or three toolbars, allow the user to turn them on or off individually by placing a menu item for each one on the application's View menu. For example, Main Toolbar, Drawing Toolbar, Formatting Toolbar. Place the items together in a single group on the menu, with Main Toolbar first (if your application has one), followed by the others in alphabetical order.
If your application has more than three toolbars, allow the user to turn them on or off individually by placing a menu item for each one in a Toolbars sub-menu on the application's View menu. Place the Main Toolbar item first (if your application has one), followed by the others in alphabetical order.
