Thanks Andrei.
My suggestion would be to write down some sort of "quick set-up guide" aside the main manual/wiki: by doing this, you would allow interested site owners to go live in a relatively short time, while at the same time creating additional interest in them, thus making them wanting to know more about the truly massive potentials and number of features that the new OSCv4 actually has to offer and eventually start digging deeper into the main manual/wiki.
For instance, by starting from the original Watch theme, a quick set-up guide should enable the user to set up a fully functional website with that very same theme, however eventually replacing the existing demo products with actual products before going live with the whole shop.
A properly-written quick guide should show how to add products and categories within the same original theme layout, while at the same time considering and explaining all the hidden relationships with other OSCv4 features and functions when doing that (e.g.: a new product will not show up among new products under the new products tab unless it has not only been added, but also marked as new until a given date and the maximum number of days for which a product is marked as new have been set).
A properly written quick guide should also take into account all those essential operations and configurations that are absolutely mandatory for a freshly installed site to go live correctly and show how to complete them one after another in a step-by-step procedure. Some examples of essential operations and configurations would be: configuration of all the essential website information, locales, currencies, how to set up tax and shipping information properly, online payment setup, etc.
Last but not least, I have tried to replicate the flushing cache issue, however, this:
https://www.oscommerce.com/forums/topic/498293-a-simple-logo-change-in-the-mobile-theme-version-completely-destroys-layout-of-the-desktop-version/
totally prevented me from doing so, because my desktop theme version has gone away and I now have some sort of "hybrid" desktopmobile theme version where all the destkop buttons have disappeared....
