As we are currently allowed only 10 pots (I believe is current number) I think it’s probably too much trouble to have folders, etc. for them. But I do agree with a sleeker appearance to them (if you have all ten, have to scroll a lot haha).
Pictures they have spoken about in another thread, and there was talks about possibly collaborating with an images website to allow us to pick from the stock - I read it as individual images each would probably be hard on the servers, but who knows 
It might be worth having a look in this thread, with quite a few ideas on the go: Pots - Feedback Thread 🍯
