1. That space isn't there on iPhones so we try not to use it to keep the layout as similar as possible. We are currently reworking a lot of things and hope to expose technical information more readily.
2. You should be able to swap the camera and map view using that button in the lower right corner. This button will swap it both ways. Is that not happening for you?
PS: 13.4 is out and fixes a bunch of UI flashing and CPU issues. So far so good.
