It would be great to get an extra field for attributes, that holds the unit of an numeric / decimal attribute.
Now you have to save every attribute, which has an unit like mm, oz or V, as an attribute of type varchar.
In very large stores with more than 2000 attributes the varchar table becomes very large and the other tables are not used, because you need the unit of meassurement.
