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.
You can create more than one template to provide layout and style alternatives with the use of the template selector.
There is no known SVG module that can be used with Acquia Cohesion.
HTML is escaped when using Drupal tokens in Site studio as a security measure, this follows Drupal core.
