Hi everyone,
There used to be an app wishlist from Shopify with app ideas that had been requested by customers and partners, but unfortunately it's gone now (support told me they still have the list, but it's internal now)

I'm a developer and I would love to get some ideas about new apps and functionalities that are not covered by existing apps!
Cheers!
