I'm relatively new to jQuery and am trying to learn best practices/design patterns with javascript. Came across this link (http://addyosmani.com/resources/essentialjsdesignpatterns/book/) and decided to try and put it to something useful.

So far I've made a notifications menu dropdown using TinyScrollBar (http://baijs.nl/tinyscrollbar/) where the user can remove an individual notification. Once removed, the height of the dropdown updates until there are no more.

Here is a demo of what I have so far http://jsfiddle.net/pSpBM/3/

I would like to know ways on how I can improve my javascript.
