On my initial import from ebay into neto my SKU's were changed to N19-14-15-6-3 for example definitely not human readable which made things worse when the pick lists only show the SKU's (but thats another request).
A reccomendation would be to link the products to a unique ID like a set length hash rather than sequential numbers and give us access to export and import it so that SKU's (which are not always a unique identifier) can be changed in bulk
This is the same for parent and child products
