The Krita VCS plugin (aka Krita VC)
A small Version Control panel that lives right inside Krita, so you can save a version, set work aside, or switch branches without ever leaving your canvas. It runs on the exact same engine and the exact same history as the desktop app. Save from either one, and the other sees it.

Parking work without saving it
Set aside parks your ticked changes on a shelf, without turning them into a version, and puts those files back to your last saved version.
It's also the fastest way past a branch switch that's blocked by unsaved work.
