When I have a file like c:\temp\foo.zip\bar.txt open and then I try to save it, Slick gives some error dialog that isn't so helpful.
How about when I attempt to save, slick should redirect to SaveAs instead of giving an error?
The saveas should default to the parent directory of the archive itself.
Better of course would be to allow saving into the archive, but I assume that doing this is harder and may not be wanted.
