jOrgan no longer offers the option, "Save As", when dealing with Disposition files.
When a user wants to make changes to an existing disposition and to save it with those changes,
it is a good idea firstly to create a renamed disposition before making any changes, preferably using
the existing name but adding a version number (e.g. "name_version_2.disposition" or
"name_v.2.disposition". A simple work-around is to copy the existing disposition, paste it to the Desktop,
rename it there, and then return it to the folder from which it was copied. This will leave the original
disposition file untouched. The user can confidently open the renamed version in jOrgan, (by double-clicking
on it), and make any changes, before saving it.
