When the new UI came out, I and other users complained that the devs removed the "show all" option, instead limiting us to 150 problems per page max. They responded by saying we could opt out of the new design, which I promptly did.
I just logged in to find that I'm back to the inferior new UI! I'm not able to find any option anywhere to change it back. And sure enough, the devs never bothered to fix that 150/page limit bug, so now once again I'm unable to use my browser window to randomly select problems from the full list, rendering Leetcode considerably less useful for me.
Is it possible maybe that option is just hidden somewhere and I'm not finding it? Not sure why my profile would've reverted back, though, unless the devs just decided to take away that option and stick it to those of us who relied on the features of the old design. Either way, I really hope they either reverse this move or make it so the new UI supports showing all problems per page like the old UI did. Depriving us of that option really screws up my workflow!
