Confirmation button for Marketplace purchases

I’ve accidentally purchased packs with my minecoins because of involuntary hand twitches on my controller, I think it would be beneficial to have a pop-up when you’re about to spend minecoins that says “You are about to spend [x] minecoins on [pack name].” With a confirm and a cancel button. This would be very helpful for people with hand issues or otherwise clumsy people.
