Presently, it is not possible to handle products that are usually sold in DIY stores or interior design markets like fabric, wood etc. as they are sold as so called "yard goods", for example 1.5 linear, square and cubic meters and so on. This also goes for the sale of working hours etc as one cannot enter non-integers.

Please enable this feature in standard functionality of Shopware, as I guess that this is a wide used functionality and thus gives SW6 more reach.
