Yes, modifying the product page with sp isn't dynamic, it's the same page vor every product, that's a very big restreint.
Actually, at this point, I see two major lacks in easystore.
- The flexibility of easystore which will be partially improved after your fix.
- The registration process which is not user friendly at all. A new customer who wants to register has to first make a user registration with validation, after that fill the personal infos and all that with ugly joomla pages. No other way than going in the code to make it look a bit nicer. All that process should be integrated in easystore and if possible in pagebuilder. I checked all the templates and nothing is close to something professional... I am too close from the deadline to use another third party e-commerce but this part is prohibitory, too far from your competitors.
Sorry to tell this but it can maybe help to improve in the future.
