It would already help a lot, if the plugin would reuse the files of a .sgu that have previously been rendered with the standalone, unless they are not explicitly rendered again by the plugin. I really don't understand why this should be so difficult. The respective files of the standalone already exist somewhere on disk and even the filenames of the tracks should be known by the plugin. Obviously, after making changes using the pugin, this would be a different story.
