Hi Peter,
Something that would be helpful as a future enhancement.
It would be nice if there were a visual clue on a file that it is subscribed to (e.g. a modified Icon). I know there is the Subscribed Content folder, but if you are browsing folder contents, it would be good not to have to right click to see if you are already subscribed, or lose your place by going down to the Subscribed Folder to check.
