Hmm. Really needs a way to save and resume editing a "shred" I was in the middle of selecting some different portions of a bunch of videos and accidentally quit. Seems like an app with potential though.
we're working on a recovery feature, so if you liked the previous shred better than a new one you can go back to it. we can probably use that to salvage the last shred in the event of the crash. thanks for the suggestion!
