Description
Generates a new script, by default at "Assets/Editor/OpenSceneNames.cs" that generates MenuItems each loads a scene from the build settings. It will ask you to save your scene, to be safe.

Place it inside the Editor folder. Then, you can click "Open Scene/Update Scene Names" and it will list, in the same menu, all scenes in the build settings.
