Hi
I think HikaShop is a great extension!
Consider people who sell download MP3's, Ebooks, Software products and people physical products such as T-Shirts, tables are two different business's that run totally different from each other.
The person want to sell download files want to inform the customer what format option they can download?
The T-Shirts want to offer easy shipping options for customers and postage
Consider how it will be better to separate HikaShop into two different extensions download store or physical good store.
I hope to see it soon!
Many Thanks and Kind Regards
Charles
