Add-on to delay seeing answer

Off-topic question:

I am trying to see if there would be an addon that would delay showing the answer of a card until X number of seconds go by. Why? Well, when I have a lot of cards to do I sometimes click too fast without actually reading the card. Making me wait “3 seconds” or so would guarantee I actually read it.

Has anyone heard of something that would accomplish that? I am not looking for an autoreveal answer. If not, how hard would that be to create? I’ve always wanted to learn how to create my own addon and maybe this will be the start.
