Remember preferred sorting option for challenges

Let Eterna remember a player’s preferred sorting option for the list of puzzles.
Right now the default sorting option for all players is “easiest” which is convenient for new players but quite annoying for those who already cleared all the older puzzles. They have to load the list twice every time they go to the challenges (first the default “easiest” list and then the “newest” list).

YES! Please do make this a feature! Thx Madde for voicing this, it has been in the back of my mind to request for a long time. - d9
