Add the functionality so that we get to choose which screen opens first when we open the app. By default it's Photos. Provide a setting so that we can either set it to Search, Sharing or Library. Showing the Library when I open Photos app is the most important thing to me, because that's where I go 98% of the times when I open the app. It's the most important place, containing Camera, Screenshots, Downloads and everything, so it should open by default in my opinion that would save a lot time.
