Now we have Pitch, Yaw, Roll and Auto (with two modes: single axis and multi axis)
It would be great to add Brake too as an input for the flaps so we can easily make aerobrakes.
Another input method that would be great is multi axis for non auto inputs. Let's say you select multi axis and then you have 4 sliders to select between -1 and 1 or a text box and you can tweak pitch, yaw, roll and brake manually.
