You use boosts as a thread to as a save function. You can view your boosts in your profile. As for hiding, you can block a magazine to hide that specific magazine in your feed, or you can block a user to hide their posts.
I don't think Boost is a good substitute for Save, since it's public. It's basically publishing your bookmarks, which may not be desirable for many. And un-boosting when you want to remove it from your saved list seems a bit weird. People could have replied to it.
The ability to hide post does not yet exist.
These are features I've also been missing.
