I am a proponent of being able to set an automatic save of my work to date on any image in process. Many people have complained about crashes and freezes during their image manipulations. This of course, can be very frustrating, in that it requires a restart all the time. I have looked for an option that would actually save all my work automatically every X minutes without success. I then have gotten into the habit of stopping work to save my work in process manually. I don't suffer problems very often, but when it happens, I am thankful, I have my backup. Would love to see this feature added.
