I should also mention that not only can you make your own custom menu bar, but you can also make your own custom menus.
Go to Preferences > Custom UI and click ‘Enable Customize’ then click the button right under it called ‘Create New Menu’. Name the menu what you want and hit Enter on your keyboard. Note: When you give your custom menu a name start the name with the ~ (tilde) character. This won’t show on the interface but it will ensure that all your custom interfaces display correctly. The new menu has now been added to the main menu bar. You can also drag this new menu into your custom menu bar and place what you want into it.
