I remember using it on B18, and I really hope it a) exists, and b) is updated to 1.0.

Basically, you could call in trade ships at will. Several at a time would come, and you could alter how much stuff they had, from barely anything to, like, thousands of whatever they had. Pretty sure you did it from the trading console or whatever, but I'm not sure.

Also, I don't know if it was the same mod, but I had one that added more kinds of traders- like one that dealt in animals, one that just had bionic stuff, one that just had statues and joy stuff, one that just sold stone, etc. It was compatible with most mods, and was generally really cool.

Also also, does anyone know if there's a 1.0 alternative to RimBank? I miss it...
