Oh nice. I didn’t know tapping the left and right would switch notes.
I think the first time I used it I tried swiping and then when swiping switched between people it didn’t seem quite right so I stopped using it. 
For example, I clicked on a person to get there so I guess I assumed swiping wouldn’t switch to a different person once I was in there, if that makes sense.
Cheers to the new feature though!
