Add separate house number field in checkout
Every major platform offers a separate field to enter the house number in checkout, rather than entering this together with the street name in the "address 1" field.
There is a very good reason for this. It ensures that addresses are formatted correctly. It is very difficult for shipping label API's to correctly split house numbers from street names in all cases for all European addresses. Shipping labels without the correct house number information leads to delays, returns, unhappy customers and a lot of extra costs for the seller.
It is time WooCommerce joined the other professional platforms and provide this as core functionality (even if it is optional to avoid backwards compatabilty issues).
Thank you for taking this seriously. Many people are not happy with this but find work arounds. This might be the one point which converts someone who is on the fence deciding between Shopify and WooCommerce.
