Please clarify some config options

Hello,

please clarify the two config options 

a) "Allow to create item if it is not in inventory?" and 

b) "Allow to give item when respawning?"

For my understanding, if b) is set to true, the NPC gets 1 piece of the item at spawn/respawn. It will use it if applicable, and throw it away once it is defective. With only b. set to true, the NPC will only get a new one at respawn, or it finds one.

But what does a) mean if set to true? In which cases is the item created? At what time? When it needs one, or prior? Does the NPC need to have the right resources for crafting in the inventory? if a) is set too true, does the value of b) matter?

A question regarding priority order: Does it mean use/create the best one you have out of the list? Or does it mean, begin with the least one, and get better from time to time? So for example, first use the stone-axe, and when it's done, create a hatched, and so on.

A little wish/suggestion: Would be nice if the list of wear items at spawn would be a list of lists [[...], [...], ...] . So we can have different clothing-sets (one set randomly selected at spawn) with only one NPC definition. Same for the box-skins when inventory overflows.

Thanks for your time and greetings,
