The EFB is way too big at the smallest size. It obscures way too much of the panel and/or gets in the way of views while navigating visually. Optimally, the smallest size should be proportional to an iPad Mini at the distance from the eye to the panel.
Please add a smaller size than the current “small.” This would allow us to keep the (detached) EFB on-screen while allowing quick glances at an approach plate or sectional chart without obscuring a GPS navigator or other vital instruments.
