Hi Rob
Thanks for your comment, still learning about pinegrow and I find some difficulty and time consuming to add codes to it for wordpress. I have though it was kind drag and drop and there is some people here have developed plugin for wordrpess.
I have been using Visual composer for 4 years and i find it quite easy to drope colmun and raws in the fly and i have test the sites on google dveloper for speed and visual copmoser do not have impact at all
The pinegrow tutorial for WordPress is quite poor that is how i feel
Regards
