Restoration

Roll back one region, one layer or the whole file without losing what came after.

Restorers clean a painting one square at a time. Restoration works the same way: brush over the part you regret and it returns to any earlier version, while the rest of the picture stays as it is now.

Nothing is overwritten. The restored region becomes a new version on top, so the step you undid is still there underneath if you change your mind again.
