When I start Audacity (with or without any audio files specifed on the
command line) and then wish to import additional audio files, usually
I want them from either the same directory as the files I specified on
the command line, or from the current directory.  Instead, using the
Import > Audio... function from the File menu brings up a file dialog
centered on (apparently) the last directory from which I imported any
audio in.  This is often a completely unrelated directory; then I must
(sometimes extensively) navigate to the correct directory to find the
files I want.  Further, the other directory sometimes has many entries
or resides on a different medium, in which case there is a noticeable
wait for the unrelated directory to be completely shown before I can
start any navigation at all.

This may be difficult to change due to users expectations and/or not
wanting to add a profusion of interactive options, but I'd like to
have it recorded that at least one person finds this behavior less
than optimal.  I would prefer that the import directory default to the
directory of the most recently imported audio file in the _current_
project (ignoring any other simultaneous or previous sessions or
projects), or to the current directory if there is no such file (e.g.,
the project is blank or only uses newly-recorded audio).
