Hikashop is an advanced shopping cart with loads of payment processors and I found it much easier to set up than other shopping carts. There have been a number of bugs in the product - but I am happy to report that every one of these issues has been resolved in less than 24 hours. The shortest response time from the developer was an amazing 7 minutes!
Nicolas and Jerome monitor the forums and provide excellent support even for the starter edition. Hikashop is a relatively new kid on the block but it is a fully fledged shopping cart and I for one shall continue to use it as long as it is developed.
A hearty thanks to the team for a first class product.
I like particularly that more than one sitemap is possible and that each can be assigned different permissions. This allows a simpler cut-down sitemap for non-registered users whilst a second sitemap provides all the links for all registered content.
I was a bit worried that if a page includes a category list this (together with all it elements - articles - etc.) is included in the sitemap. This extendss greatly the length of the sitemap and just complicates matters. However, the developer's notes do indicate there are levels of configurabilty that I hadn't spotted. A little digging revealed the extensions tab - and the content plugin. With Expand categories set to "Never", only the menu link is showed and repetition of content is avoided.
Documentation could be fuller.
Fine control over layout is restricted: a very large menu translates into a very long list that does not break over columns.
Other than that, top marks to the developer for an extension that installs easily (great for new Joomla! users) and works well.
