What it adds:
- An arrow beside each problem listed in the module you are viewing, and also besides your module progress.
- On hovering over the arrow, you are able to view a list of the progress of the people that you follow, along with the date when the progress was updated.
- Similarly, in the popup, you are also able to check the number of problems that a person you follow has done today and the number of problems that the person has done in total.
