• Added a new Configuration Section called "settings";
• You can now choose if to enable Banknotes Merge feature, and if not, if to make banknotes stackable or not;
  
• You can now choose if the plugin have to Check for Banknotes items name and material or not, could be nice if you want to change material to make so players can use old banknotes anyway;
• Added /Banknotes Give command. You can use it to give banknotes to other players [Admin Command] or to give them using the console (Usefull if you have to give them from other plugins, such crates plugin)
• Fixed a minor dupe bug with merge feature.

I suggest you to Delete old config file and then copy old "banknotes" config category back to the new one to avoid any sort of problem.

Now it is possibile to stack banknotes even inside other inventories without any problem.
