PlanetsCentral

I want to use the unload command to transfer money to an unowned planet. Am I correct, that this cannot be done with the PCC2 interface, or did I miss something?

There is no user-friendly interface to do that yet.

The reason is that things you unload still occupy space on the ship (unlike for the normal unloading), so I'm still undecided how an interface for this command could look like.

However, PCC does understand the command, so you can manage it using the "Auxiliary Commands" window (Alt-E on main screen).
