I built one of those. Twitter's API isn't going to do you any favors. There is no publicly available API to get the replies to a tweet. So building out a full thread is hard. Then once you figure out how to use their internal API you'll quickly hit rate limits </3
I'd prob use Twitter more with an RSS style client, akin to NetNewsWire.
I have zero interest in retweets, replies, threads, hearts, etc.
