F/ O Button in Tracking Station

[simtom]

Hello,

It'll probably be obvious when I know what it means, but for now I can't seem to figure out what this button toggles in the Tracking Station:

[Double Timan]

Also wondering this

[MechBFP]

It’s a mystery to everyone. 

[Kerbart]

Is it a message?

[JWag]

I pressed it and it just turns grey. Was kind of hoping that it would've changed between "F/A" and "F/O".

[simtom]

Huh, weird then!  

[Periple]

I'll worry when it changes to F/U!

[Fluke]

@Dakota Can you enlighten us?

[Dakota]

Whoops! That's not supposed to be there - good catch. It's a placeholder for an unimplemented feature and currently does.....nothing!

[The Aziz]

So it's going to do something in the future in some way.

Brainstorming time it is.

Was just going to post Fuel/Oxidizer. My Google fu is not strong today. Only other reference I could find was a NASA deep space tracking network handbook from 2016 that lists F/O as Fiber Optic.

Dont know what the F/O would be but Im guessing its relating to supply routes from the resource update? Thats the thing I can think of that would be both useful for the tracking station and would make sense to be toggleable.

Fuel/Ore? IDK man

I'm going to guess its a button to track which vessels are currently under force or thrust. We're in for some very very long burns for interplanetary travel.
I sent a craft with infinite fuel and accelerated to 1132 km/s and it took 900 years to reach the edge of Kerbol's SOI. 

[J.Random]

Probably related to floating origin (frame of reference). I'd gues it's for navball alignment and trajectory visuals (nodes and values like Ap/Pe) in the binary system.

[Tazooka]

I'm going to guess its either:

Something to toggle between ships you control and ship that are automated,  part of the colonies update (like refuelling or something)
or
Ships that are not burning and ones that are, for the interstellar update

I can't think that F/O would mean, but I like this idea

Happy to see I've started a hunt for what it might be
