Well, So sad and sorry to write what I am writing. I spent hours working on PrestaShop to find the following.
1. Database design is **bad** -- If it depends upon row IDs. Period.
2. Front Display is not configurable from any menu, it requires code changes to increase the number of products in a row.
3. There is no SLider Scroll within the prestashop unless you pay to find out that it breaks something else.
3. There is no Documented Import or Export details. It is left for user to figure out who must have a programmer level understanding.
4. Full screen or width control is poor.
5. Its Core is heavy duty inert code, which badly affects performance.
Yes it is a good learning tool for a programmer but not ready for any prime time. Most folks who started to use it in 2014 and paid for modules - ended up wasting their money. When I click on their stores links in 2018 - they are all broken links. That tells us a lot. Well ... looking for something better and stable. Wish me luck ... No pun intended. At least this was a good start.
