Request for CoBlocks food and drink: a Dairy Free icon and an icon key. Since not everyone uses exactly the same icons for things like "vegetarian" vs. "vegan", it's helpful to let people know what means what. (In general, though, I love the block, as I have a client that has a restaurant as one of its services.)
