Many product types
Can somebody give me any advise how to organize store with many product types?
For example we are selling laptops, mobile phones, headphones, auto parts etc.
Each of product type have their own characteristic to filter it.
Also products should be imported to store from CSV file (maybe from only 1 file).
I can't understand how better organize it, to make one product type with many displays, or many types with one display.
How to organize it to make comfortable categories and comfortable filters.
