I would like to see an order history for accounts to make re-orders simple.
I would also like to see the items consolidated so resins can be ordered by a drop down menu with first Machine type then below that quantity. The same with tanks and build platforms.
Currently if you order the site will jump directly to the shopping cart and continue shopping brings you back to the default page (Form2 items). This recently caused me to order the wrong tank.
IMO simpler is better and no need to jump pages when ordering.
Just my 2 cents,
