Here is a list of the jQuery plugins I use the most.
GSAP: Professional-Grade HTML5 Animation
GSAP is a suite of tools for scripted, high-performance HTML5 animations that work in all major browsers. No other library delivers such advanced sequencing, API efficiency, and tight control. Stop wrestling with cumbersome CSS animations, stuttery jQuery.animate() calls, or a system that limits your creativity. Use animation to tell a story in a rich way rather than settling for a few fades and slides.

A jQuery inline form validation, because validation is a mess
When it comes to form validation, it’s hard to have a versatile solution that works with every form. Figuring out how to display errors is not a simple task. This is something I tried to remedy with this script. When an error needs to be displayed, the script creates a div and positions it in the top right corner of the input. This way you don’t have to worry about your HTML form structure. The rounded corner and shadow are done with CSS3 and degrade well in non compliant browsers. There is no images needed.
