I have realized I can do this on my macbook at home but can do with my other one at work (both el capitan both chrome latest version). So is this a bug?

why is the odd dimensions starting with white? twist?

Please support "alt/cmd + right/left arrow" on editor screen.

Thanks, also should mention output of tests seems to cut in half.

Hello there. Trying to solve it for javascript but getting "Max Buffer reached: Too much information has been written to stdout." in random tests after permutations of an array of unique elements with length 9. Really liked it by the way.
