Hi Steven,
I noticed it had appeared on the WordPress Dashboard for the web version. I think that it may be linked to Jetpack because before the changeover to Jetpack for analytics it was not available on the web version.
I’m currently using the Quadrat theme on my site and added a project to the portfolio which I have linked to the navigation so if you want to see the page generated by this Portfolio it is live now at https://brandonljballard.com/portfolio-2/
I only have the one project right now but I was able to see that it’s possible to arrange multiple projects on a page in a tile format.
I only recently noticed it on my dashboard so it could be that it is a new feature. I’d like to link it to whichever plugin it is associated with but I never installed it in the first place.
Thanks
Brandon
