jQuery

Using Zend Framework convinced me to try Dojo. Experience with Dojo convinced me to use jQuery. Dojos strong constructive structure is its downfall requiring an immense number of downloads and the bundling system is exhausting and doesn't completely obviate the problem as you still are stuck with a huge number of CSS fiiles -- and its a bit buggy to boot.

So I'm running with jQuery. Here are a few libraries that I have developed - they aren't too specific to jQuery but they are designed to be used by custom jQuery components.
