Foo is a developer tool that offers a blank template with pre-wired widget functionality for ease of development.
One of the best things about foo is that it is completely free of charge and distributed without a license. So you don't have to worry about attribution or any other legal concerns.
But what about features? Well, foo has plenty of those too. You'll get a fading "i" button, a "Done" button, automatic version string generation, a working random() method, xmlHttpRequest implementation, debugging methods, and more!
All in all, if you need a solid starting point for your widget development, foo is a great choice. It packs all the features you need to get started and is flexible enough to grow with your needs. Give it a try and see for yourself!
