After getting through the first island I have jumped around a bit. While looking at different missions and their stats I can see that there is a large number of individual who attempt and less that actually solve, which will always be the case, but I think there is a flaw. I don't know how many different problems I am currently a statistic on because I clicked solve it and started to program a solution, got side tracked and never came back to finish it. Is there a way to know what missions I have tried to solve? or maybe a list of problems I like or maybe want to solve in the future? If not I think this might be something nice for possible future development.
