If you could somehow organise a calendar functionality so that I could just log in and see my daily/weekly requirements that would be a massive tipping point.

I would happily pay for that. The clunky export to Google Calendar does not work that well and it relies on tutors have the file for import to begin with.

I typically partake in 2-3 MOOCs and another personal dev course at the same time.

Calendar type functionality = my $$$

Great product BTW. Love it.
