I guess any reasonable user would understand that files must be closed, windows must be synchronized, but for pt2pt things are different because two sides are involved. Marking them as complete is only enough on one side, they should be matched in the other in order to really disappear. Thus, completed and matched make sense …

Yes -- for p2p only.  :-)

(we're violently agreeing, I think)

Yeah, or a reference to it.  Nathan and I will cook up an errata proposal.
