|A new button is added to the FC-lists of ships and planets: click it to set a random friendly code.|
You can set a list of charactes you want to use in the settings section (stored on your computer). Set an empty list there and press save to add some 80 characters of all sorts (default value). Be careful with special characters like quotation marks, because I can't say whether they're safe to use.
Attention: if you don't like your random friendly code, switch to another ship/planet and back or no new random code will be created!
