Hi Andy!  I agree with the idea of putting the config file in the
~/.openshot folder.  That makes perfect sense.  However, I wanted to point
out that this config file is in no way related to the overall data structure
of OpenShot.   XML is a good format for this config file, but it's only
going to store "config" settings... not the entire schema of a video
project.

That should be a separate conversation . =)

MLT has it's own XML specification that OpenShot complies to.  Also, the
internal project structure in OpenShot is a binary serialized structure (for
better or for worse).  Although, we can convert this into a ASCII-based file
if needed.

The MLT XML that OpenShot generates is ideal for transforming into other
formats, reports, etc...  However, no work has been done on that front yet.

Thanks,
-Jonathan
