There is a way, but it is hidden about as thoroughly as it could be.
You have to hold down the shift key while hitting the extras button, then recognize that "write project summary" actually saves the scripts to a text file. Of course, there is no way to get these scripts back into scratch, so it is only useful for looking at them.
Quite frankly, I think that the use of "shift" with on-screen buttons should be eliminated from scratch---it is a decidedly unfriendly and arcane interface style.
