The developer can put an option for hide : "more tweets"
I made a ublock origin filter for this. :
! More Tweets
twitter.com##[aria-label="Timeline: Conversation"] h2>div>span:has-text(/^More Tweets$/):upward([style^="transform"])
twitter.com##[aria-label="Timeline: Conversation"] h2>div>span:has-text(/^More Tweets$/):upward([style^="transform"])~div.
The developer can also put an option to disable “Show more replies,” button Thank you.

This really cleans things up! The only feature I hope gets added is the ability to block retweets in Lists.

What a great addon. Removes all the clutter and cruft that Twitter has built up over the years, gives you back a nice clean simple experience without metrics and all that wasted space. I also like it will stop you seeing people quote-tweeting those you've blocked, stopped the "This tweet is unavailable" message. A great simple addon, thanks very much! Highly recommended if you're a Twitter Web user.

pls update

It's perfect ! Thank you !
