Testing version: 10732
What were you doing: Viewing Notes column in app
What feature did you use: Notes column in app
What happened: The bottom divider line of a single note is larger than the others
What did you expect to happen: All dividers to be the same size.
You most likely have a to do box checked in the note with a thicker divider.
I do. Is this the intended behavior?
I believe it is. When you use checkboxes in a note, there is a progressive bar to show you how many of the checkboxes have been checked. Once all of them are, it would be a solid horizontal line, slightly thicker than those notes without any checkboxes.
Yes, the separator doubles as a progression tracker for your ToDos inside the note 
Thanks for clarifying! Sorry for the false alarm.
