Hey guys can you put the blue border back in place, this way it shows whether or not it is a character that you should already know by now or not, the neutrality of the blue border will give a better sense of the progress for new characters, in my opinion.

Blue is now used for grade 4, "too easy". We were thinking of putting a lighter red or pink border for "don't know", but held off at first because of feedback about confusion. We can try putting it back and seeing what people think; I'll put a to-do for that.
