The new look has certainly grown on me. The unlimited number of problems beats all the discomfort due to change; one can have a glorious binge in a particular area now :) There is not an unlimited supply, though... I hope the paucity of problems in calculus is the exception, perhaps because it's a relatively new category? I still wish all the problems are more rigorously arranged according to rating, though -- so that one can locate the desired level with more ease.
With all that said, Brilliant never disappoints; I am the one who needs adjustment.
