Allow attachments to be public/private like case comments
Under Point Threshold
There are instances that certain documents/files are useful for individuals within the specific company to see but should not be available for viewing by the company's clients.
It is my understanding that the ability to make an attached document/file private will only allow the person that designated as private to view the file/document.
Making a attached file/document private should work in the same manner that case comments are able to be seen by those working for the company and hidden from the company's customers.
