Viewing other participants’ code is extremely useful and mind-opening. However, sometimes I need to take a second look at the problem description or maybe I want to copy it so I can share it with a friend along with the different proposed solutions. But there’s no way to go back to the description after a clash has ended.
EDIT: it would also be useful to add a link to the problem page (not just the description in plain text) so we can go back and try solving it in the editor (with the test cases and all), once the competition has ended. Sometimes I want to go back and check some code changes, or sometimes the time ends when I’m close to a solution and I would really like to finish it, even when the competition is over.
