three pens. they're under the paper when you tap today's doodle: thin, medium, and one thick enough to draw with a fingertip, which is what most of us are doing. someone asked for this, and they were right. the pen you pick stays picked, and a mark you come back to hands you the pen that drew it. the hand is steadier too. a slow, careful line no longer keeps every wobble your finger made, and a long one follows all the way instead of stopping halfway across the page. the usual quiet tidying besides, nothing you should have to think about. three lines a day, as ever.
