Another issue when filling up the product database:
Imagine 3 products A, B and C. A is available in colors red and blue, B in yellow and black, C in red and black.
As far as I understand I have to set up the product attribute color three times, always having 2 options and then link each product to the corresponding colorset... This will become really ugly, when having lots of products with lots of different colorsets all just named "color:" in the properties list. Confusing, isn't ist?
So the best way would be to have only one colorset with colors red, blue, yellow and black and then being able to exclude options in the product view.
Lokking forward to see what you think and happy to discuss any questions on this topic with you.
