While studying FLHook source got an idea to build Craft plugin for it.
Using some cargo components and special shipyard/craftyard give player a possibility to create commodities/weaps/stuff. Crafted items wont be accessible through wrecks or traders and will have better stats than their analogs(weap guns for example). And ofcourse add some randomness for item generation.
In general:
-> Exec craft command. Give crafted item or not if lucky. eat required resources from cargo.
Such plugin will require to add ALL crafted items to .ini files (that's what I fear and hate).
