Hey @Liza! I love the idea, it seems so cool!
I only find one little problem.
Won't this make HS less challenging, and less creative? People may think, "Now how do I code this for my game? Oh wait, I can just use a picture."
If you want a good coding app, don't make it too easy. I'm probably not subscribing, but if I can earn the money (my parents wouldn't give it to me XD) then honestly, I'm not going to use pictures unless it's the point of the project- that it includes pictures.
I just think that it won't encourage creativity and challenging work. Because all the subs can just... use a picture.
