Paypal Button Before Checkout?

So a customer complained that they didn't like to have to put all their information in during our checkout since they were paying with PayPal. Hadn't really thought much about this as I don't complete checkout too often on our site except when testing. But customer totally makes sense as with all the mobile users these days they don't want to fill out all that information if they are paying with PayPal as they just want to log in, pay and move on. Am I missing something on why PayPal doesn't work that way with CS? I have the Amazon Pay add on and it works that way. Customer just hits the button before ever putting in their information (either on the cart or checkout page) where the simply log into their account, pay and they are done. I have been on many other websites that work like this using PayPal so I have to be missing something. ???

Configure PayPal Express Checkout payment method. In this case customers will see Checkout with PayPal button on the Cart page

Thanks! I knew it had to be somewhere. Just wish that button was also on the checkout page too like my Amazon pay is so if the customer skips the "view cart" page they still have that option.

You can en able the Settings -> General -> Allow checkout only from the Cart content page option

I gonna try that out and see how my customers like it but not really what I'm looking for.

I understand. But additional custom development work is required in other case
