Yes, would be good to get ONE page builder that supported CP. I think if just one of them gets on board, and is known as the one that works with CP, then they will get all our business. Same with a security plugin. They all do much the same job, so if WordFence won’t come to the party, I’m happy to go with whoever does.
It would be interesting to start a list of categories of plugins we feel are important, and then see if we can get at least one CP-friendly version in each. Might just do that.
