There is also a great mod here: Link
This gives you a lot of new commands that let you do basically everything as far as items, inventory, crew, and various settings in the game, as well as a few admin helpful commands.
I'm not sure if it works server wide if you put it on a server. I'm going to check that, though I'm hopeful that the server config lets you specify who has access to specific commands.
In singleplayer it does everything you need though basically, if you dont want to use dev mode.
Also -- I am curious about this trainer, because it says "RETIRED" on the trainer status page. Does that mean this trainer wont be ever updated again?
Its only in early access so I was hoping that they just tagged it RETIRED until it is released, to avoid constant updates for an EA game (which I agree would be a waste of CH time).
