Remember Saved MP File Name

It would be great if Gryphon remembers the name of the saved MP file.

When I select "Save mp..." in the File menu I'm given a dialog box with the file name that is automatically populated based on the SCHEMA name regardless of the name of the original file.

I expect "Save mp..." to save to the file that was previously opened without a dialog / auto populated name. The current implementation is more like a "Save as mp..." and it may make sense to rename to that.
