Pretty much every cart I've used or installed has a "Redirecting to Paypal" lightbox popup or interim page.
Why?
Because paypal is painfully slow in responding, and the customers will click and click and click on the buy button, thinking nothing is happening - IF you do not have the redirect notification.
So, pleeeeease can you put some kind of redirect notification into estore so we do not loose impatient customers who think the estore cart is broken.
Thanks
