Well, nothing is perfectly easy.
I have a little tool, sort of a clip, that slips over the next-to-last
link at each end of the chain (or thereabouts) and holds them against
the force of the derailleur's tension arm. This makes it easier for me
to fuss around getting the ends of the chain to align before either
driving in the last pin, or using a quick link.
