i have added the guest view by my own:
pretty hardcoded... just removed the login check and all settings page stuff
works so far but hopefully you will add this to the core script

Pretty Easy:
Go to application/controllers/app.php
and add these lines to the end of the index() function
$this->session->set_userdata("loggedin", 1);
redirect('app/dashboard');
the login page is gone now.
then remove everything which should not visible for guests from
application/views/dashboard.php and sidebar.php
best regards,
