It would be very helpful to save different versions of a project without saving the whole media every time. This would save much discspace and time with bigger projects.
Or make an option to use linked media outside the project-file.
FotoMagico is using a technique which is called "Hard Links" while saving the file. This causes the file not to be duplicated if the file is on the same physical volume. If it isn't working on your machine, I am wondering what machine, what file system you are saving on?
