Two parent styles (light and dark) are supplied. You set both styles as parent styles, and then create children from them and you can make edits to them. And you will already update the parent ones when new versions are released.I'm really interested in buying this! Does it come complete with parent and child styles? I always have issues with that. So I import the parent style, then the child, then edit the child? And then I can "upgrade" without loosing my changes?
