See exactly what changed between two saves.
Opening two .kra files and flicking between windows is a slow way to find one edit. Krita VCS lets you pick any two versions from your history and look at them together, with the parts that actually changed marked for you.
Side by side, or under a slider you drag.
Pick two versions and view them next to each other, or drag a swipe slider across a single canvas to wipe between them. The slider is the one most painters end up living in: it makes a repaint or a shifted silhouette obvious at a glance, because your eye compares the same spot rather than two spots.
Zoom and pan stay linked across both sides, so you can go in close on one eye, one hand, one edge, and stay there while you switch versions.
Changed layers get a dashed outline.
Krita VCS reads your file layer by layer, so it can tell you which layers moved and which sat still. Changed regions get a dashed outline, and untouched layers are left alone. When a painting has forty layers and you only touched three, you find those three immediately.
That also means comparing does not depend on you remembering what you did. The file remembers.
Compare across branches, not just down one line.
If you branched off to try a different palette or a different pose, you can compare a version on that branch against one on your main line. It is the honest way to choose between two directions: look at both, then keep the one you actually prefer.
Nothing is thrown away while you decide, and nothing leaves your machine.
