When crafting recipes that require water. Can you make it so it's possible to simply right click a water barrel and use the water from the barrel for the sake of crafting?
As for flour. Why is a stack only limited to 0.50 kg? We should be able to stack more or perharps make barrels/Create a new kind of container for the sake of holding flour. Perharps some bag made of Straw or Plant fibres?
Also this is a long shot but... How about adding an item, like a Handyman belt? It could add 4-5 spaces in your inventory where only tools are allowed? It would save players a lot of time and trouble to constantly swap between tools/weapons and bags.
Or perharps create keyboard shortcuts that easily allow a player to swap between two set of items.
Create a new building called Cooking oven or something. That is only placeable inside houses. It would require oil to start the fire.
Oil could be made from barley seeds or perhaps create a new kind of plant for that purpose. There would be a slot in the UI of the oven where only a frying pan can go.
Oil could also be used to make new items like a oil lamp. Wall lamps. Could also be used as fuel to light up other things.
Perharps oil could be a part of recipe to create new improved cooking recipes.
