@pfefferle – In “block themes”, the “read more” is a Gutenberg block; in the “classic themes” it is a tag, anyways the main suggestion is to give bloggers the ability to control how, where and when the post will be truncated. Through “read more” block/tag, a certain number of characters/words, a single paragraph (the closure of a /p html paragraph tag), the post excerpt, whatever parameter could be implemented – I’m really sorry I’m not a coder, I can not go beyond suggestions.
