Breakdown notes also comes with some helpful keyboard shortcuts to not use the mouse as much. This was added not so much for flowcharts, but to make it easier to write notes quickly.
-Tab to add a new figure on the canvas
-Enter to add a new paragraph in the shape
-Arrow keys to move a figure
-Shift arrow to move between figures
You might also like www.breakdown-notes.com. It is not as focused on diagrams as draw.io (and others), but is rather nice if you want to make something inbetween notes and diagrams. (so I say as the owner of breakdown-notes).
