Trade Window - "Need"

[Gov McFly]

What exactly does the "Need @" column represent? If it is needed they sell for more/buy for more or what? Be nice if there was a tooltip for it.

If you save a ship design with the resource tracking on, that's what it does. It's a neat tool to make sure you get the resources you need from traders to build the ship without resorting to external notes

Note: This is AWESOME by the way.

So, build a new ship. Doing that 'erases' your old one and you have all the resources it's made of to play with, plus what's already in your pocket.
Now, build it. Make it sexy. Do what you want.
Then save that design.
Doing this lets let you set what it needs beyond your ship value and inventory value...
Which means, when you are buying from folks, you get a countdown of how many materials you need for that design in that column.

ITS EFFIN MAGICAL, YO.
