I can't imagine this is a big effort on the part of the programmers, but how about an "export separated tracks" option in the file menu, so that all tracks are exported as separate wav files in a single location.
You select the location, and all tracks are exported into individual wav files with one click of a button. I know this would make all our lives much easier.
By the same token, and in the same dialog, it would be nice to select "midi" or "wav" for the export option. So that you could either have all separate midi files or all separated wav files.
