“Nice to have:
It would be nice if we had some basic styling options for the place order button (e.g., background color, hover color) to make it blend better with our theme. Maybe these would be plugin settings that then get passed as arguments to your server when you fetch the button.”
Agreed. My store’s theme is pretty far removed from the button’s default styling, so the button “as is” sticks out like a sore thumb at a critical point in the checkout flow.
