Yeah 3.1 is just the beginning of the coupler rework, it will be improved gradually over the next few releases. We also have an inline style coupler in development.
Re. parents, we currently use the > hotkey and this conflicts with blockquotes. I generally always add a space after the angle bracket to create a blockquote however this isn’t always required. How would you feel if we made it the same behaviour with this hotkey?
I’ve modified this to be a feature request so we can keep track of this better.
