Would love to be able to hear the sound of the tools on the paper in real-time as I draw. This would have to be done extremely well in order for it not to be gimmicky (e.g. changes in pressure, tilt, and angle would have to produce seamless and realistic adjustments in sound and volume).

I would never have imagined myself requesting this feature, but it’s been done remarkably well in Tayasui Sketches Pro. The real-time sounds create a surprisingly immersive and soothing drawing experience that I haven’t found in other drawing apps. (They produce an almost ASMR-like effect and offset some of the strangeness of drawing on a screen.)

I wouldn’t want this feature in every drawing app, but it would be a great fit for Flow (especially as it’s created by Moleskine, which has a strong sense for how things should ).
