when you're in a contest and the site is overloaded and requests take a long time and you already live in an area with bad internet like me, and you want to go to the next problem with a single click you need to either have the main problems page open so you can open any one quickly or have the complete problem set open.

I think it would increase accessibility if there was a convenient way to go to other problems within a specific problem page.

a drop down menu is also good that allows you to go to any other problems, not just the next/previous one.

what do you think? have this thought crossed your mind before?
