I started using the Charge theme from your Site Library, and I started editing the Element “Home Hero”, messed up the template, but couldn’t find any way to revert to a previous version. So I checked the Pages function, and couldn’t find any option there either.
Before I started using GP, there was always an easy way to see past saves and choose the one you wanted to revert to. I can’t find any way to do this with your interface.
