When I access a network folder using nautilus it shows up in the Places sidebar, but not in any other application's save/open Places sidebar. Why the inconsistency, and how can I add a share so every application has access to it without having to edit fstab?
By default network shares are mounted in the hidden directory
With this tool we are also able to mount network shares as a non-root user in any newly created folder in our home directories. For a short explanation on how to use it see this answer.
