Just found a is Japanese site with three stylish themes. For those of you who prefer more colour. A Bitwig theme, Live theme and something called Cream Salmon. These are all free. Currently the themes should work in 10.1 and 10.1.1 (though I haven’t tested them myself). There is also an ES2 skin if you’re interested.
