When the setting should to reduce the noise for users who select text while reading, it no longer helps.
The share button was added for logged-in users. The AI plugin adds an “ask AI” button. The design experiment adds a copy button. On posts that you are able to edit, there is an edit button.
So, if you disable the quote button, only one of the buttons disappears.
I think it should be possible to either disable all the buttons or none.
