I am looking at the HikaShop Feature Comparison chart:
www.hikashop.com/extensions.html
and I can't understand the meaning of 1,2 or 3 stars in the columns for each version. I understand a checkmark or no checkmark. But some columns have 1 star, some have 2 and some have 3. What does it mean? Is it in some way related to the stars associated with each version of HikaShop as shown at the top of each column? What does it mean, for example, that Custom fields for products has 1 star in the Essential column and 2 stars in the Business column?
