The Notable Pros (Because they are so many)
Super flexible and scalable with its excellent smarty-like template system and custom fields which are easily edited right within the administration. Great that different templates can be assigned per item, per category.
The Attribute system is supreme and idiot proof (debatable) and further extends the flexibility.
Can function simultaneously as Catalog and Cart where VM is one or the other.
These guys get it when it comes to online shopping cart. So much flexibility I thought I was using a Magento enterprise system!
Lacking 'perfect' documentation so a lot of logical figuring and Googling has to be done, but the same can be said for numerous components. Documentation or technical writing takes lots of time and usually requires totally separate staffing to do that accurately. Give it some time. I would rather the developers spend the time perfecting the functions and let Packt Publishing and other such services develop a manual.
Keep doing what you do redTeam! Your innovations are dynamic and well appreciated.
