It seems like some mining materials are not in that expansion trade materials(cobalt, saronite, etc).
Could I pull this and commit something you are missing in new branch and then push it here?

Absolutely, there are lots of missing items, this is something that takes a long time to build up, and I only started doing this at the end of legion, so there's lots to catch up with.

Nice! So as I use this addon alot, I'll start updating it when I find something that bothers me.

I cloned repo and made new branch. I added gathering professions and some tailoring ones to your code. Could I get Permission to upload that branch to git? Then I'll make pull request and you can check code with your PHP scripts.
I'll add more like jewelry and stuff while playing.

You should have access now, let me know if you have any issues/questions :)

Closing old issue
