great plugin for ajax add to cart

this plugin is great plugin . thanks . but i wish after clicking “add to cart” button it :

1- open a pop up that shows what you have in basket and their title and size and had two button’s for “checkout->” or “continue shopping ->”

OR

2- go to the top of page smoothly and dropdown the shopping cart and show items in cart

if in admin panel it we could choose between these two options it would be real 5 star plugin . thanks
