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.
No. Helpers are coupled with the page once placed. Changes to the Helper layout will not affect existing instances.
Color tags allow you to create groupings of colors based off of the color tags that you define in the website settings color palette.
You don’t have to add units unless you want to use a specific unit or you’re adding Custom CSS properties.
HTML is escaped when using Drupal tokens in Site studio as a security measure, this follows Drupal core.
