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


Can you share the code needed to do this? I might like to tinker

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,
