WOW Adam - Great work!!  I've just skimmed through the post and its looks like a great enhancement.

Just to summarise, we need to map the security config file to each role in DNN?

Does this restrict access / viewing of folders to which the roles do not have access, say when uploading or selecting a file?

Ideally, when navigating through the folder structure, it would be great if the Editor would check to see if the current user has the required DNN folder/file permission to access / upload files..

Thanks again for your work on this - you're starting to pick up a great following in the DNN community!!

Cheers,
Andrew
