improve sidebar task, using jQuery ajax for all actions
This kind of code can be easily broken, what if we change the layout of the sidebar item. I think, a better way is, you give the sidebar li item an id (which would be the item name), then for remove and reorder, you done't need this ugly parent().parent() thing. Also, you can have a span wrapper around the name of the sidebar item, so to update name, you just find this span element and change it's content. yeah ?
