Edit without fear
Every move in the editing room is one undo step, and Revert to Original brings back the untouched recording no matter how far you went.
Make a mess
Trim the start, split the take, delete a piece. Three real edits in ten seconds, the kind you make while finding the shape of a cut. Nothing here is scary, because of what comes next.
Walk it back
Tap Undo and the deleted piece returns. Again, and the split heals. Again, and the trim is back. Each edit is exactly one step, and Redo walks the same road forward. Your whole session is a two-way street.
Or revert everything
Revert to Original is the big lever: one confirmation and every cut, reframe, transform and mute is gone, the take exactly as you recorded it. And since the dialog says it itself: even the revert can be undone.
The original file never changes while you edit. Done saves your cut beside it, never over it.
Make a mess
Cut boldly. The worst case is a few taps of Undo, and the very worst case is one Revert. The recording you made is always still there.
