Highlights include a CSS3 version of
$.fn.animate, a text range plugin, swipe gesture support, and a version of
jQuery.event.fix that uses ECMAScript 5 getters.
There are discussions about the project on Hacker News:
Wtwui (GitHub: wtw-software / wtwui, License: MIT) from WTW Software is a collection of UI widgets influenced by UIKit by TJ Holowaychuk. It currently includes a dialog, overlays, tooltips, and a confirmation box. It's built using AMD, so each component can be loaded using RequireJS.
The project is tested with Jasmine, and it includes a build script built with Node.
jSignature (GitHub: willowsystems / jSignature, License: MIT) is a fork of brinley / jSignature with additions and tweaks by Daniel Dotsenko.
jSignature allows signatures to be captured in a browser, and works on touchscreen devices as well. Older version of IE are supported by FlashCanvas. A special effort has been made to capture smooth-looking signatures, and it supports extra editing options like undoing the last stroke.
