One of the must have plugins in my arsenal

This is an amazing, stable, solid, flexible plugin like few others. Its helps me get so much more out of ACF pro, makes writing that frontend code much easier. The only trouble I have is that the documentation is vague at some points and its really hard to get support (how to query a related field, how to understand which fields are actually usable with which parameters, etc.). The finer pathways are for me difficult to navigate and I would actually pay for a tutorial three times the size of the actual one. Besides: Marvellous.
