Affects: nautilus (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
If you decide to share a folder, the sharing emblem should be appended
to that folder.  This will be a nice visual cue to know which folders
are being shared.  There is no way to tell if a folder is being shared
currenly unless you access "Sharing" and view the checkboxes.
