Hello Ernie, since your app has so many ways to customize things, I thought these suggestions would also be helpful:
2-Finger swipe left =. Add note
2-Finger swipe down = add picture
2-Finger swipe = add sound
All these swipe commands would be related to the card that is being swiped on. I'm constantly adding media to the cards so this would be helpful. It would save me 3 taps on each card.
Thanx!
