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.
There is no known SVG module that can be used with Acquia Cohesion.
Yes, the component link field supports both internal and external URLs.
No, the entity browser does not work for component defaults as the entities are content, not config.
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.
