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? 

@Gargron

I already bookmark threads I really like, the old-time way. But if people want an in-house version of it, why not?

(I'm super-vain, so I hope it'll allow me to fave my own ramblings, too. :D)
