The new rich text editor still confuses me when it comes to newlines and quote blocks, in months since it's been gradually rolled out, I still can't remember if it's Shift+Enter or Enter to end the quote block and what kind of newlines work with quotes, if it's the selected text or a hidden paragraph that quotes are applied to and so on. Just let me edit the raw markdown as before or expose the underlying markup model when editing.
