Hi Patrick,
I thought that hiding the direct link would help to stop sharing, but I guess sharing the actual file is not much harder than sharing the link. Perhaps it’s slightly harder!
– The list shortcode still exposes the link via the button, right?
– Only for logged-in users might help. Perhaps not so much for my site, since anyone can set up an account — but again it’s another step sharers have to go through, so that’s good.
Again, thanks for the plugin. It’s nice and clean, I like it.
