Can I revision my templates, styles and components?
Yes. You should revision your Acquia Cohesion assets like other configuration using a service like Git.
Acquia Cohesion renames to Site Studio from version 6.2. Tell me more.
You can create more than one template to provide layout and style alternatives with the use of the template selector.
Google maps may not be showing if you have not set a Google maps API key.
You can use Elements to create content but we don't recommend doing so for multiple reasons.
Cohesion layout revisions are created at the same time as node revisions, but not always deleted at the same time.
Use the "Node Revision Delete" contributed module to manage your node and associated Cohesion layout revisions.
Use the tools included in the "Entity Reference Revisions" contributed module.
