By default, submissions for a problem are shown in the increasing order of solution size. (Example). Why solution size, of all things?
This becomes annoying when I want to look at some readable submissions for a problem. Look at the the first entry, from the above example. No line breaks whatsoever. The code seems to be specifically tailored to top this list. No offence, it's their choice.
But as a user, I think order by submission time would be more natural and helpful. That would first list the code of the contest toppers. Given their consistency, it becomes a lot easier to find their solution to almost any problem.
At least, is there an option in the settings to change the default behavior, that I might have overlooked?
