I share/deliver video and other media that is hosted elsewhere. You can embed video to preview, but in order to share a link to be copied for use by clients, I would have to add it into a text block. That's OK, but it could be slick to have clickable buttons or a drop-down menu to copy the links to embeds. It could sit somewhere that follows the logic of your UI. Also, I sometimes deliver branded and unbranded versions. So some control to add additional links per preview would be nice.
