The gesture for deleting a character from favourites is annoying, everytime I swipe to scroll, I get the popup... A long press would be much less error prone, or just allowing the deletion only when youre in the Favorites and not in the normal view. Also, the screen rotates when the phone is upside down... Look at Apples stock apps like safari, notes and SMS, they dont pivot when upside down, and this means you can use these apps in landscape mode when youre in bed or on the couch, because the orientation will stay landscape even when youre lying on the side. Very important detail for me.
