Industrial systems seem to be woefully under-represented in the commodities market. About all they seem capable of making is Domestic Appliances and Consumer Technology (don't confuse them with refineries which make metals, many of the Industrial Systems are also refineries).
It would be nice if there was another category added for Industrial Systems so they could offer more variety. Perhaps "Parts", which might include all sort of things ranging from machine parts to motors and engines, electronics etc (the "Industrial Materials" category would seem to fit this, but if any stations sell these, I've not seen them)
