Playground "light" theme

Great site, and playground is really cool. It even works great with the arrow keys on my iPad Pro, something most online editors like cloud9 and Visual Studio Online have trouble with. I have one small issue however.... The sun started to shine in Amsterdam, and with sun on the iPad Pro screen, letters on a dark background are unreadable. It would be so great to have a switch to enable a light theme (and maybe even font size) so I can enjoy the playground in the sun... isn't that where playgrounds are for... to play in the sun:-)
