Hi Nicolas,
Thank you very much for your post, it is informational, courteous and well explained like always.
Unfortunately I have to disagree 100% with your opinion about Hika Styles and optimized templates.
The Styles are a must have, not in their actual form as they are more related, if you allow me, to Joomla 1.5...
I agree there are more and more templates styled/optimized for Hikashop...
Because I bought one you can trust me 100% about my comments below.
Unfortunately these optimized templates are not styled for Hikamarket and even worse they have poor, little or no styling at all even breaking the original (nice) layout of other installed Joomla components.
In other words they are simply useless if you do not want to spend days or weeks to custom style the layout of these other components...so where the advantage of buy such templates?
Because of this the "Hika Styles" have a significant importance !
I would a thousand times prefer to buy styles than templates...
Talking about styles I am NOT referring to colors but to nice effects on products divs, list, etc...
Also a correct display respecting the browser window size, I am referring to this now old thread :
Affichage Div sur tablettes
Styles can please everybody, templates will only satisfy a few!
If fancy and "up-to-date effects" are included I guess you will sell much more "styles" than templates.
