Mentoring: In the listing of "New solutions", it would be nice to see some sort of visual cue if you have mentored a student before

Perhaps even a number of exercises you have mentored.

Furthermore, if the "new solutions" list was personal to each mentor, it should bump up the solutions from people who you've been mentoring

... oh well, you could even go further and personalize the list in a way that based on the feedback the solutions are promoted on the lists of mentors that the student gave highest ranks to because it IMO is quite subjective what a person considers constructive feedback... 🤔
