I think it should be possible to share a playlist link even with people who do not have an account in Kitsu.

YES! It still not works Xx

It would be great if it was possible to share the playlist with vendors also, so they can see shots they work with in order together with other shots that might not be assigned to them.

So as long as their user is logged in they would be able to access the playlist from the link.

Another way would be able to "assign" playlists to users so they show up in another tab in the playlist-page's list of playlists.

Thanks for the suggestion!
