It seems to me that if a template is meant to be accessible to the agency that the template should have an option to utilize/implement directly from the template library. Currently there is only Hide and Preview. In this instance I found a template that would be helpful, could not do anything but preview it, went to the subaccount where I could not find it at all-- the template does not specify whether it is a funnel or website, so I looked in both locations. This was colossal waste of time and effort.
If the template library is for viewing only and is not functional in any way and the templates are not available anywhere else then it doesn't need to be there. ( I did have your support team look and confirm that the templates I found in the library were not available anywhere and were just "looky but no touchy" templates.
