I'm not sure if this idea wasn't discussed any time before, but I have a suggestion to admins: it would be wonderful to have "Notes" section on each problem's page.
For example, now I'm solving problem 403, I stopped doing it currently and I'm going to return to this problem next time (maybe, after several days or weeks). I spent a couple of hours on it and got some results I don't want to forget. Paper sheet where I've written them is very easy to lose, so it would be very useful just to write general observations I found online in my private "problem 403 notes" section!

You can limit the maximum number of symbols here to 100, for instance. In this case if all users would fill notes for each problem to max - it will take about 6 TB of memory. I don't know whether this is a lot for you or not. If the answer is "yes" - you can also set additional limits, for instance, each user can have at most 20 problems with notes at the same time.

Nice idea. I'll add it to my to-do list.

Cool, thank you!

I sincerely hope this wonderful idea hasn't been forgotten.

I have a very "rambling" problem solving style where I scroll back and forth through the archive stopping every once in a while to ponder one of my many back (way back) burner problems. Sometimes a few quick ideas come to me which I would love to sketch down before moving along. Being able to do this right on the problem itself would be amazing!

I have a private "gist" on gist.github.com where I sketch partial results and ideas which need development. Obviously it's not an integrated UX, but it's an adequate means of accessing my thoughts on multiple devices without polluting my git repository of actual solutions.
