On your second point about Shopify, maybe someone at shapediver could fill in here about the coming integration? 
The existing integration, as you say Armim, creates a new product for each configuration that is being put in the basket as a kind of ”saved state” so you can go back and continue the configuration, but it makes a mess of the products in your shopify dash. It may have to be like that for some things to work, i dont know? But i can imagine having some good trafic and alot of products it is impossible to navigate your products in the Shopify dashboard. What I can read about the upcoming integration with app builder the app you create in shapediver will popup as an overlay on your productpage and you can add it to cart/basket, but is the ”saved states” stored in shopify like it is now or somewhere else?
On the first point we agree
About textures, for me it works great as it is. But I work with big products with wood, concrete and steel. From the perspective point it looks really good and life like, if you zoom in on my textures to like 10-20cm away there will be pixels. I could probably update the textures in size now to get rid of some pixels on extreme zoom. My problem with textures was the mapping tho, but thats how Rhino works. I havent worked with a CAD software earlier that smoothers out textures like Rhino does, Revit and archicad for example atleast keeps the texture ratio
