Do I have to use IMCE?
No. Acquia Cohesion allows the site builder to select, either use of IMCE or Entity browser for browsing and selecting images.
Acquia Cohesion renames to Site Studio from version 6.2. Tell me more.
If you’re trying to rotate the element front on, use the Z rotate property.
The style preview may not be updated because the refresh icon hasn't been toggled to the active state.
No, the entity browser does not work for component defaults as the entities are content, not config.
Yes, this is possible by creating a custom element.
