I've fixed and added a few things:
* error message is now displayed when uploading image in wrong format.
* dashboard displays left side menu section on the right side when using a small screen.
* you can switch between like and dislike.
* you can now disable certain sections in the dashboard which students can access. (see "Disabled sections" in "Even more" ). The following dashboard sections can be disabled:
Mailing list subs
Private messages (hide only)
Topic subscriptions (hide only)
