"The fact that people have to resort to searching on the internet just to find the help menu is a testament to the failure of iTunes"
Good point (though I wouldn't go as far as "failure"). It is surprising that Apple haven't followed the conventions used (for example) in Microsoft's Office products where Help (via the question-mark-in-a-circle icon) is always available in the UI irrespective of the user's choices of enabling/disabling the menu bar, toolbars, ribbon, etc. Having the menu bar default to disabled also seems counter-productive - Apple may see this as "simplification" but I can't imagine that any users, other than those who make the bare minimum use of iTunes, would not want to have the functions available via the menus available at all time.
https://www.apple.com/feedback/itunesapp.html allows you to submit feedback with respect to bugs, errors, omissions, and enhancements to the iTunes development team (though the degree to which this influences development is a matter of conjecture).
