Hello,
Thank you for your feedback. It depends on how you wish to manage the permissions. You do not need to set up permissions for each document type - you can configure the permissions globally for all document types if you use CMS Content permission matrix. Alternatively, you can configure permissions on the document level in CMS Desk -> Properties -> Security. The document-type permissions are only intended for those who really need to use them.
You can find more details here:
http://www.kentico.com/docs/devguide/index.htmlWe will consider the role copy function and summary report for future versions and fixe the documentation.
Thank you.
Regards,
Petr Palas, Kentico
