Am I alone in thinking that it would be confusing and unnecessary to have a "save for later" feature in the form of "favourite" as well as "save for later" in the form of "bookmark" side by side? 


@tobypinder @Gargron I think favorite (star) is more commonly used as a replacement for "liking" a thing, and ensuring the author gets the feedback.
I'm not sure how many people use favorite to get back to say a link they found useful and but wanted to look at later...
