Removes food, junk, weapons and armors from loot and containers. You choose what to remove.
Still not completely tested, yet more a concept than a working mod. Should be safe for quest items.
When you loot a quest related container mod will not remove any item. Quest items can be found even outside from quest related containers but mod should not remove them in any case.
Use it at your own risk. If you find any bugs or have a suggestion please let me know.

How to customize:
- open file and search for "//EDIT SETTINGS HERE"
- follow instructions

Console commands:
-HideRubbish (toggles mod on, mod is on by default when game starts)
-ShowRubbish (toggles mod off)

To do:
- Remove everything from villagers houses, even alchemy ingredients.
- Test a bit more the mod (currently doing it).
- Remove at all food and useless junk from the game.
- Merge ingredients and those few remaining "other" items in one tab.
- Add gems (very rare to be found but purchasable from some merchants).
- Restore just a few weapons and armors to specific containers in suitable locations.

Why:
Geralt wasn't a scrap merchant or a thief. He didn't break into villagers' houses to steal their food.
He didn't gather animal skins or bottles of water with him. Didn't take everything he saw around him just to sell it to a merchant later.
And I also find it difficult to believe that he could find thousands of swords and armors during is journey left there just for him to come and pick them.
