Looking forward to trying this. Came here after seeing Nookrium's YT video.
Ah good to know :) Just a thought about the PDF. Where you mention heart, spade, etc in the text putting the symbol next to the work would help at the reader's eye as to where the suits are mentioned. I know that is a lot of work though :)
Also, could be helpful to mention the goods cap of 20 near the beginning. I just realised the Warehouse increased the cap from 20 to 100.
