Item attributes is a good feature, confirmed by the customers, in order to hold the item specification information (colour, sizes, storing features). Also it has translations available, though it is not clear where they can be used, except filtering.
In order to enhance this functionality, it is needed to have
1. an item attribute overview matrix (it is not sufficient to have filtering options in item list)- that would serve as item comparison
2. an ability to provide a printout as an addition to sales shipment- either to make an option (print item attributes) or to make a separate report.
