I have setup this extension for a small local newspaper site and works great! it saves a lot of data usage displaying only what needed in a clean and mobile template. Touch menu works great too, just be shure to publish modules with information in mobile positions.
I needed to place "Meta Property" in the Head of my K2 pages in order to add moderation to Facebook comments plugin. First went to Settings and ennabled Facebook Scheme, then went to "Global Tags", pressed New, then pressed "Facebook" menu on the right panel, and data was filled in one clic. I just had to paste my Facebook app ID into the "Content" box and meta-tag was created (don´t forget to save). Tried other plugins, this one did what I needed.
