Provide students with easy access to their own time-spent data #1496
Description
Some courses collect time-spent estimates from students.
A request from an O1 student: "Toivottavasti jostain voi seurata omaa kurssin ajankäyttöä. Olisi kiva nähdä omaa statistiikkaansa." And indeed, it would be nice if students could see (summaries of) their own time usage (e.g., per assignment, per module, total... other ideas?)
