In the Sculpt section, I really miss easy navigation between front, top, side views, preferably in orthographic mode, with a hotkey to switch between orthographic and perspective.
In Blender and ZBrush you can hold a key to snap to a 90-degree view: Alt in Blender, Shift in ZBrush.
Alternatively, easy hotkeys for orthographic front / side / top view would also be very welcome.
