You mean like a cursor that can be moved via TrackIR instead of mouse? That would be very nice.
Another thing i had in mind...having a cursor that is bound to the cockpit's 3d coordinates instead of the screen's coordinates. For example, that would enable us to place the cursor on the gunsight controls and it would stay there regardless of where we looked. The cursor might be out of view but unless the mouse (or mouse emulating hotas hat) moved, it would stay there. It would be like having a virtual hand instead of having to always look at what we want to manipulate, quite useful for setting up things in advance.
For example, i might be looking over my shoulder but still adjusting my gunsight brightness or range by moving that mouse wheel. Or, i could be expecting one of my fuel tanks to run dry, so i could place the cursor on the fuel tank switch 5 minutes ahead of time...just as the engine begins to cough and sputter, a click of the mouse or roll of the mouse wheel and the next fuel tank is selected.
I guess this would be more useful for twin engined aircraft or bombers, ie flyables with increased amount of controls. Clickable pits or not, i doubt anyone would want to click the gun triggers or other important controls like flaps, throttles, etc, but it works quite nicely for less important controls that are used less than often in the duration of the entire mission, as it minimizes the amount of needed keyboard shortcuts to map and memorize.
I'll stop here, before we derail this from a "WiP discussion and screenshots" to "ideas about the interface of SoW"
