The Level window is opened when you press the Level button in the General page.

It allows you to select the playing level to use by default for new libraries.

The same windows also appears as the Reset To Default window when the Reset buttons are pressed in then Indexing, Chord Types, Scale Types, or Searching pages in the Library Options window.

Here it allows you to reset all the setting on each page to the collection of settings as defined in the Default Options.  There is a separate collection of default settings defined for each of Beginner, Intermediate and Advanced level, so you must select the level you want to complete the reset operation.

Intermediate and Advanced playing levels require ChordWizard Gold Edition.  The Silver Edition operates only at Beginner level.
