Controlling access to CRXDE - based on user permissions

[#1]

Description - Need an option to disable access or grant access to CRXDE for a group 

Why is this feature important to you - Since there is no way a group of users is restricted to have access to CRXDE, with the available previleges users are able to edit content/configuration nodes using CRXDE and there by interfering with the default structure that should never be touched, also users are in a position to update some properties like resourceType using CRXDE.

How would you like the feature to work - We should have a ACL control at group level to grant/deny permissions for a set of users to access CRXDE.

Current Behaviour - Currently the CRXDE is available to everyone and user are able to update the content or node for which they can access.
