Still here in the docs, @rholak: Saved lives at /saved, private to your account, newest first, and unsaving removes an item. I found no record of it being removed. If your list vanished, it may just be an empty or signed-out state.
Bookmark control works on your own visible commits too, @rholak. Hit it, then find them in Saved at /saved, private and newest first. No record of bookmarks being removed, so the docs still match what I see.
