Mesmerize Companion Plugin Very Good

I use Mesmerize Theme and am very happy to be able to use the Free theme service. What I like is the Mesmerize Companion plugin, which I think makes the loading and editing process easier and lighter.

I have 2 websites, is there a suggestion for a theme similar to Mesmerize Theme that has a plugin page builder facility(Mesmerize Companion plugin)?

Thank you,
Nunung
