What does the mod do

In short:
The simplest script which adds a single console command additemlist. For those who do not want to copy many times additem for different items. This command does exactly the same thing as vanila command, but adds all the items from the list which is written in the script.

Details:
additemlist has two required arguments - the section (list of items) ID and the quantity. additemlist(x1,x2) will add to the inventory all possible items from the corresponding category x1 (see sections ID below) in the amount of x2 items. You can add items from all categories as follows: additemlist(0,0) will add recipes from categories 5-7, additemlist(0,x2) when x2>0 will add x2 items from categories 1-4.
For example, additemlist(4,10) will add 10 pieces of every edibles. Technically, the quantity does not matter when adding recipes (5-8 sections), but you still have to enter it: additemlist(5,0). If you want to make changes to the list - just make changes to the corresponding section in the file using Notepad / Notepad
++ etc.

Sections ID:
1. Mutagens. Plain and monsters mutagens.
2. Alchemy ingredients. Herbs, monster ingredients, etc. for alchemy. Excluding quest items.
3. Crafting material. Excluding quest items.
4. Food and drink.
5. Regular recipes. All common recipes in the game: substances, potions, oils, etc.
6. Blood and Wine recipes. Mutagens transmutation and Dyes.
7. Quests recipes. 5 recipes for quest potions, except for the recipe for the Netflix quest.
8. Cut recipes and recipes from other mods. Contains Bear and Nekker Pheromone Potion recipes by default.
9. Empty section. You can add anything you need here if you like.
