Greetings.
Binding the crafting scene to the main menu via YEP_MainMenuManager has specific instructions in the help documentation for doing it, and using those same instructions, I am able to bind it into any slot, and access it just fine.
Menu Name: Ramza.CSParams.MenuString
Menu Symbol: craft
Menu Show: $gameSystem._craftingShow
Menu Enabled: $gameSystem._craftingEnabled
Main Main Bind: this.commandCrafting.bind(this)
This works in any of the other slots for the main menu manager as well. Note that none of the text in those boxes are enclosed in quotation marks, none of them are strings, they are all to be eval'd.
