As you certainly know Webshop as such loses its functionality. It is easy for some small things but lacks additional features like adding date fields, sync does not work with some servers due to php settings, it is impossible to add custom code for some banks for online payment (https keys...)... Mobile preview is not nice (leave us the option script design, as with the contact form, there are more and more online queries for stores but yours does not meet the needs ... Please think about it and start seriously upgrading this application which has a lot of potential.
