Re: One Piece Mega Convo (Spoilers!)
Oda said once (and by once I mean
about 10 years ago) that he had a 3 week buffer between chapters. Things may have changed since then, but he definitely does. It seems logical to say that all manga-ka do, otherwise things would be too stressful. This way they have time to fix things up and meet with the editors, instead of having to get the chapter from nothing to ready-to-be-printed in the space of 7 days. And that's assuming that manga-ka work on weekends.
And about Robin's powers, she's certainly smart enough to come up with those uses. Sometimes an intelligent grasp of a power's scope can do the same thing as unrestrained childlike creativity. But I think that it's a matter of concentration. Creating a complete clone would probably cause far too much mental stress for Robin to withstand. As it is, just keeping a hundred wings in existence while flying is too much for her to bear for more than 12 seconds, because of the physical and mental stress. However, if she disciplines her mind, Robin may eventually begin to make more complex copies wth her powers.
Though controlling another person's body would be hard, since that would take a lot of physical strength, and I think that physically, Robin isn't extraordinarily strong. And there's a distance limit to her powers, 200 Hana-Hanas, I believe, so setting up eyes and ears all over town would be difficult. But within a 200 Hana-Hana radius, it should work. But again, having a lot of body parts that far away would probably cause her a lot of mental stress.
