Wow, is anyone still using MooTools? :-)
Yeah, this library is very, very old - I haven't done any updates on it in many years.
However, I have actually been working on a rewrite in TypeScript - it compiles to vanilla JavaScript with direct DOM manipulation, so it's faster than this old library, and will work with any library including of course MooTools.
It's usable, but doesn't have all the functionality of the of library yet. I probably should pull myself together and put out an alpha release though...
