This of course is an excellent component. Once used to it, it makes adjustments to your site very versatile. However, take some time to learn how to use it (let's say the dark days between Christmas and New Year's eve.. :-) ) so you get accustomed to working with the component. I am sure that in the last days I only got a glimpse of what it can do. And yes, documentation is not very extensive. However, in the Forum (community.getk2.org) you can get a lot of 'answers'. If only someone would convert all these forum discussion to a nice set of documentation.
