The new polygon obviously will not be perfectly adjacent to the existing one and I need a tool that clips (and fill) where needed (the new polygon)." Using the "avoid intersection of new polygons" and the "reshape tool" it can be done, but it is bit tricky, especially if the "common" border has a lot of nodes. I agree that a ad hoc tool would be better.
