I often like to include Code examples in my Google Docs. However, in Google Docs, it's very hard to present code in a way that is readable. This is where Code Blocks come to the rescue. After installing it, you can easily format your code. Best of all, you can format your code according to language. For example, you can select CSS or PHP and it will format the code in the style of these languages. Review collected by and hosted on G2.com.
No real complaints. It has an option called "theme" where you can select a colour style for your code. This is really handy, but it has too many options and can be a little cumbersome to browse at first. This is only a very minor quibble as you get used to it very quickly.
