Another great feature is, when creating a new data type, you do not have the notion of Joomla article fields and additional fields. You assemble your types out of a list of data elements and arrange them as you please.
Combined with the easy front end layouts, you put your custom fields wherever you like in what ever order you like (almost always without programming) they make short work out of customizing your views.
I value support and am happy to pay for it, especially with a component that plays such an important role on my website. Yootheme's support has been excellent and I am thankful that I have the option to buy it. A CCK without the option of paid support is too risky for me. I don't want to have to scratch and claw all of the web for hours or days to figure out if something is a bug or not and how to solve it.
Updates and new features arrive at a pretty consistent rate which also gives me great comfort. And, I feel that the Yootheme team WANT feedback and listen to it. I am a very satisfied, paying, customer.
