Google makes your code prettier
Something I'd love to see Microsoft do more of is small, simple, solutions to annoying problems that would delight customers. Here is a perfect example.
A simple Javascript and CSS file, the Google Code Prettifier makes syntax highlighting in a web document super easy. It's pretty flexible too. According to the project page , the lexer involved will correctly highlight code written in C, Java, Python, Bash, SQL, HTML, XML, CSS, Javascript, and Makefiles.
