Great job on the teacher dashboard! The icons for the links and overall organization is superb.
I like that you put in custom text too for links. It helps explain where the link will take them and what they might do there. Example " Import content from another course" instead of just "import". The end user just knows they want to grab something from another course but if they just see "import" it might not trigger the thought to click the link. Whereas your link further explains what the link does.
Great job.
