Currently, if you open several files for batch processing, and then run a batch (let's say an Amplify), the batch runs properly, but then it automatically saves all the files. It seems that it should not save the files unless you select to Save All Files. Currently, if you run that batch, and then realize you made a mistake, you then have to Undo that Effect for every file, and then select Save All. This can be very time consuming with a large batch of files. There should be a setting to change this behavior if preferred.
