This repo is just a collection of small addons that I use regularly in my MooTools projects, things like adding shuffling capability to Arrays to just convenience methods that can make code more readable.
I have the source code separated into separate files depending on the Class they extend, I will also keep a YUI compressed version of the all the addons in the Docs directory.
I will try to keep this document up to date with addons that are in this repo and I will keep the source file updated commenting the usage of the addons.
Just include the needed files on your site and start using the methods.
If there are any addons that you find yourself using often in your project please fell free to fork this project and contribute what you can.
