If you ask me, commands such as:
'Activate Auto-Shutdown'
'Exit'
and 'Restart' (if implemented)
have nothing in common with a 'File' or music library (collection of the files) as it refer to MusicBee or the computer (system) in general.
I suggest to move those commands to a separate main menu entry or assign them to 'Tools' eventually. The 'Tools' menu could be renamed to 'Management' or sth like that. IMHO, the current solution isn't quite intuitive.
