I installed this plugin hoping it would assist in adding a jquery dock fixed to the right site of the browser window of my WordPress site, even though it isn't intended for that.
Surprisingly (to me) it worked :)
1. Install the plugin.
(This merely assists in not having to manually install the jqdock.js and call it from the functions.php, but that's good.. yes?)
2. Choose a dock style on http://www.wizzud.com/category/jqdock/examples/
3. Paste the jquery and html code from Wizzid into your header.php (after the body tag) and the css into your theme's style.css (or child style.css) and format it with your own styles.
Voila! Mac-style dock
