New option for fuel transfer

[Chi]

Right now I am building a spacecraft in kerbin's orbit, and after attaching an extra fuel tank to the main tank I transfered all the remaining monopropellant I used to dock the extra tank. When transfering the monopropellant, I ended up with one side of the ship with the containers full of monopropellant and the other side of the ship with half empty containers. That's when this idea came to my mind:

Why not have a new option to balance fuel between 2 tanks?

Sometimes you need to transfer fuel from one side to another, but you also need to keep the spacecraft's balance, otherwise SAS can't stabilize it. It gets even worse when transfering big ammounts of fuel, as it is harder to get it balanced. This should be pretty simple to do, just run an algorithm to compare which tank has more fuel, add the value of fuel from the 2 tanks, divide it by 2, round it and apply the value to each tank... or something like that.

Oh, and here is a screenshot of the DUNA-X with only one extra tank docked:

I hope I can get this thing to Duna and come back in one piece

I'd like to see a 3rd option. balance across Center of Mass. Harder to do with more RCS tanks. But its doable eventually

Yeah, the problem with that option is that sometimes it is impossible to do such a thing. For instance, if you look at the screenshot from my DUNA-X, it would be impossible.

Have you tried this?

It'd be nice to have fuel tank options for action groups, even just a couple of basic things like empty (sends to other available tanks), fill (draw from other tanks) or even fuel options on decouplers (empty stage, sending all mono/LF/O above stage)

The link I provided is to a mod that does all the things you want. Balance across selected tanks whilst at the same time emptying selected tanks and filling other selected tanks. You can highlight tanks and choose to send fuel out, lock them, balance them, pull fuel in etc

Very nice mod, but the point was this being implemented in the game itself. I also don't like how modders usually add more windows to the game, a simple context menu would do just fine. Still, thanks for the link, I might consider using this.
