Good idea #[1] .
These options would be useful:
1. Mute thread
2. Mute forks from the thread while the direct responses to the initial note are shown.
And, taking this a step further:
How about a notifcation tab that shows this:
⏹️ Note 3 --- [x new responses]
⏹️ Note 2 --- [y new responses]
⏹️ Note 1 --- [z new responses]
Then you can click on each note subject:
⏹️ Note 3 --- Visibility Options
[Full thread] - [New responses] - [Likes]
[Mute thread] - [Mute thread forks]
