I was recently was inspired to work on Kwicks for jQuery v1.5.1 by Jeremy Martin because it hasn't been updated for a few years. So, I ended up changing the plugin structure to make it easier (for me) to add a getter, setter, event hooks and custom events.
Check out the demo. Hopefully there is enough documentation to make adding a kwick to your own site easy! Download Kwicks for jQuery 2.0 here.
