Recently the behavior was changed to automatically anchor the note to the current reference when hitting the New Note button. This is preferable to never doing it automatically, but it does tend to create anchored notes where that wasn't the intention and doesn't make sense. I would like to see this respect the most recent note per notebook. For instance, I have certain notebooks that inherently tend to have unanchored notes. When adding a note to these notebooks, it makes sense to add an unanchored note.
