The new UI has a very low contrast, where everything looks grey.
It's very difficult to read, and also depressing.
Meanwhile, I don't mind much about the change on layouts.
That's why I always use the old UI.

On Oct 9th, 2020, my UI was changed to the new UI automatically and I can't change it, which makes me create this thread to let Leetcode know that the old UI is important. This is seriously a big issue!
