Along those lines, is there any specific documentation or list for the gk- helper classes and syntax?
For instance, I didn't even know the gkCols class existed.. and only found gk-wide-image by dismantling a demo page... that's terribly inefficient. I am sure there are others. I spent a fair amount of time - futilely trying to build a columnar layout with bootstrap classes, to no avail...
Also, the Layout Manager mentioned in the Gaven docs does not seem to exist in Gavic PHOTO.
