is there something i can do to change the names.. like refined metal, not many players know this is hqm. maybe we can use ingame names or pictures for the resources needed that dont cause confusion for player

"metal.refined" is the short name of the resource ingame. Since the price can be altered the function of the script that returns what is needed to craft it looks at the players inventory and lists the resources missing by shortname.

It's theoretically possible to embed a dictionary that parses it into the proper names at that point but it would add unnecessary overhead to the function. But honestly it's a lot of extra work to do and would be a problem for any other language set-up other than English, so I'd rather not. 

The code is MIT licenced though, so if you know a coder that has enough time on his hands they could add the functionality and release a forked version, and by the licence terms they could even sell it.
