Frankly, right now, it's a bit of a pain to make nesting material for your lionesses. It takes too much clicking and it's annoying to browse the dropdown menu to find which kinds of items you want to use.

What I thought to solve these problems is to make it possible to craft nesting materials right out of the stacks in your hoard. There would be a dropdown menu giving you the choice of how many nesting materials you want to craft, in case you need to save some of the items for crafting decor/ applicators/ etc.

That would save time and make it easier to use up items you dont really need, which can be a problem with the current mechanics if you have a huge hoard!
