questions about Joomla eCommerce template

Hi Ivan, I didn't quite understand you regarding the scale...

About my 2nd question, will it be possible to use two templates with the site, one for viewing from computer and tablets, and the other one for viewing from smartphones? Also will it be possible to program the site to identify the device and redirect to the appropriate template?

Another unrelated question: how easy to use is the template interface. especially to add new products or to edit existing ones. We want it to be simple enough so that any employee in the store would be able to edit the site without difficulty.

We don't have such concept for smartphone layout redirection. We use "Responsive" layout concept.

Product editing does not have anything to do with template.
