They added shaders and object dragging feature to Plane Crazy. Here is the keybinds to do that:
-----------SHADERS-----------:
shift + p = activate freecam
shift + backspace = lock camera in freecam
shift + z + enter + m = secret shader 1
shift + z + enter + n = secret shader 2
m in freecam = lock wasdqe movement
hold ctrl in freecam = temporary speed increase
-----------OBJECT DRAGGING-----------
Hold r and move the mouse to rotate
Hold q or e to rotate left and right
Hold r and use the scroll wheel to move further away or closer
Hold t or g to increase the height or decrease it
Sadly, object dragging doesn't work on mobile :(
