I love how easy it is for people who are new in business or have little experience with this kind of things can make their own store like any other professional website that has been developed by experts! Sometimes some functions could be improved (like search bar).
Also there's no mobile version available yet but we always keep our eyes open about updates from developers side as well so hopefully they will improve those missing features too soon :) Definitely try out all possible functionalities you want your customers/users see during first few times when starting up - everything counts and helps making them familiarized enought while trying something which might look odd at beginning. We wanted to use more modern way than traditional wordpress solution without loosing functionality. It was important point because most likely user base would not understand what do mean "wordpress" means if used only one simple phrase :D.
