I was unable to help the customer reach a resolution because of endpoints that are unavailable to myself and the inventory features are not available to the customers.
Two major issues that I have had support calls on is:
1) the ability to alphabetize items within a category. Items are displayed in a category as they are added and there is not a way to alphabetize the items for quick selection.
Both issues are the most common that customers had contacted me about. I sent this identical message to firstname.lastname@example.org and was told to submit it here so the engineers will get it.
