Just consolidating the Canadian ‘wishlist’:
Critical
bulk upload of products
multi-lingual capability
flexibility in tax categories/calculation
Important
bulk upload of customers (esp for tagging purposes - like member lists)
box builder feature at least - maybe more full CSA support (social media interfaces especially)
UX overhaul - especially flexibility in how products display for really large product lists
Nice to have
route planner
way to help hubs find and make delivery arrangements with other local producers/hubs/shippers (such as a crowd sourced list of delivering options perhaps?)
