I just uploaded the new version of the Ambition theme. You should have Early access to it. I will soon update the Theme Demo and Documentation pages next, but you should already have access to the latest version and all of its features.
You can download from your account page, then once installed go to the “Child Theme Setup” under the “Genesis” tab in your Admin. Once you click the “One-Click” installer you’ll see what the new demo will look like. Much easier to make edits.
