Show quantity added to cart

Hi!

On line 118 of the plugin code the item added to cart message is generated. Is it possible to add a variable to that message to show the quantity of products added?

I’ve tried googling for a way to do this, but I’ve had no luck and my jQuery skills aren’t up to that level. I don’t know if it could be done in a simple way or if it is a complicated task.

Thanks!
