The component has an easy and stable API, and this year with all the new add-ons, but most important, the Incubator‘s new plgugins the whole extension have become very very flexible, just limited by your creativity.
Suggestions: Tutorials for newbyes and just for reference. The forum is big, but a little difficult to find a proper answer from the knowledge base.
Lacks: offers from the joomla community for templates commercial or non-commercial.
In general, i recommend this extension, and want to thank for the work done.
