Submit and Moderate Revisions with the Divi Theme
Divi is one of the most popular page-builders in WordPress, and it does integrate with PublishPress Revisions Pro.
It is possible for lower-level users to edit a page with Divi and submit an update for approval.
This image below shows what a user in the “Revisor” role will see when they update a page with Divi. They will see a small “Submit Revision” button in the bottom-right corner.
This next image shows what a site administrator will see when they go to approve a revision created in Divi. They will see the page layout in Divi, with the PubishPress Revisions approval bar on the top of the screen.
Note: it's not possible to schedule revisions from the frontend of Divi yet. This is because Divi doesn't have a “Publish Date” field on the frontend.
