Yes.  It should do (the equivalent of) a `mv`
on the current directory.  And the Dired buffer
should then be refreshed using the new location.

And yes, it should ideally keep all settings:
omitted files, markings, whether details are
hidden - everything.  The only thing that
changes is the location of the directory.
