Hi Shapeways, Just now, I've begun listing a new item. The new way the product interface is structured is a little odd, but everything new is odd at first, right? I'm sure I'll get used to it. What I WON'T get used to is, instead of going through a list of materials and turning ON the ones I want, instead I find myself going through the list turning OFF all the materials I DON'T want. I'm sorry, but this is just so silly. If I design a ring in stainless steel, I shouldn't need to go turn OFF every other material in every possible one-by-one (there was no 'Disable All' button that I could find). This is just a little ridiculous - I do hope a 'Disable All' button is in the works, and very very soon!
