As part of the WISP, I intended to release a full UI package called BalfUI. BalfUI will include both BalfPick and BalfSlider and will be fully modular - using my website, you can pick exactly what parts you want and receive a minified package of CSS and JavaScript containing just what you need. This was actually requested early last year, and I had originally considered it but decided against it. BalfUI will also include a flurry of other things, including BalfRibbon; I'm hoping for an early release of my Phoenix Font and other UI elements.
All of my projects are open source and hosted on GitHub for anyone to use. BalfBar also features a menu generator on my website to simplify the generation of the HTML.
