Edit burn node vectors without gizmo

Burn nodes should be able to be edited in a window or any other way not involving the gizmo. The gizmo is great but a massive pain to use when you want to center your view on the map to some far-off planet as you carefully tweak how your craft will intercept and travel through its sphere of influence. For instance: if you are fine-tuning your path to graze the atmosphere of a body you are not yet within the sphere of influence of. You are forced to manually drag the camera to the target body to view your trajectory, and can only edit the burn by using the widget which is now across the solar system and viewed at a very troubling angle. Adding the 3 axis sliders into an on-screen window as a part of the UI would fix this.
