The Tree view is the main attraction of the plugin. This creates a hierarchy solely based on the file names in the Vault. If a level in the hierarchy is missing, an orange dot will be displayed next to it to indicate that there is no corresponding file to the note.

Example: You have a filed called dev.csharp.access-modifiers, but you do not have a file named dev.csharp. That will display a orange dot next to the csharp level in the hierarchy.
