The Disc menu tool
If you open this tool while a menu is selected, it is equivalent to opening the Clip properties tool; otherwise, it provides a Create Menu button that takes you into the Classic Title Editor to begin the process of creating a new disc menu.
Because developing a menu is a relatively intricate operation, Studio takes the opportunity to remind you that pre-built menus are available in the Album.
When you decide that this reminder is no longer needed, check the Don’t ask me this again box before clicking the OK button.
