When using a digital planner one is often switching between writing and navigating. Each switch requires one tap the button in the upper left.
I am right handed, it would be nice if there was an area on the screen that I could hold with my left hand that would activate the link following options so I could navigate the planner and then when I lift my finger I can write again. For a lefty this would/could be on the right side of the screen.

For example, it is the weekend, I am reviewing previous week(s) and planning the upcoming week(s). I am using DashPlanner, perfect for me, and that means I could be looking at 8-10 different pages, following a link to each of those. As I review a past week and a thought comes to me that I need to record, rather than reaching for the top menu I hold an area on the edge of the lower left of my iPad. it gives me access to links, I navigate to the page I need, lift my thumb and I can write again. Hold that area again, navigate back to the previous page.

I realize it isn't much to tap the link/writing button on the upper right, but it would be a little faster and more convenient.
