Open directory should use the parent if there's none in the current
Use cases
When selecting 'Open Directory' in VLC I navigate to the dir I want, but then have to move up to the parent to select the one I was previously inside.
Desired behavior
If the currently viewed directory doesn't have any directory's inside of it then the parent should be used.
Benefits of the solution
Quicker for those with bookmarks and 'starred' directories.
(IMO) More intuitive as you select the directory you're currently in.
Possible drawbacks
Inconsistent for users (One might not realise that they can select the pwd if it only contain files).
