iOS interface is fairly minimal, but it works most of the time.
A few small features to consider
1. Swipe left / right (or up /down) to go back / forward
2. Click on number to call. I have a lot of people's telephone number in my Brain, and it would be a huge time saver to be able to click on the number and it to load the iOS "would you like to Call this number" dialogue.
Thanks as always.
Thanks for the suggestions. These are both documented already.
