2. remove the limit for the amount of pinned problems (wanted to compile a list featured on hn / favorite in the euler forum for example and there were more than 25) / add different colored pinns perhaps
3. more advance filtering of diffculty(range wise) / clickable in the bottom of https://projecteuler.net/progress
4. weekly problem(other than the new recent problem) perhaps released this week x years ago - in order to encourage more leveling out of "solved by"(discourage numerically solving. This could help recalibrate the diffculty of a problem
5. Add the diffculty to the problem page
6. Graph of problem number by how many solved (simillar but different from https://projecteuler.net/problem_analysis) as there are some anomalies (perhaps by some of the awards)
7. make those graph more interactive / bigger perhaps?
8. a way for users to rank a problem to find cooler problems
9. go to random problem
10. go to suggested problem to solve (Based on matched tags solved? ranking?)
Thanks
