In Twitter and within the browser there was Twitter decks. You could make a deck to follow an account(s). It generated columns and each colum would put a new post at top when it happened. For me it was not that intuitive. Then again I could never figure out Twitter lists as easily as I did on Mastodon.
Decks was really good at keeping you up to date with a hashtag as it happened.
Had friends in the path of a couple of hurricanes and it was nice getting a live updates for the area.
