To be able to convert any blueprint into the amount of slots needed as well as the weight needed in resources
Example: you find a really nice blueprint but you notice that it will take alot of resources... you need to know if your smithy can hold the resources within its 75 slots ... or if your Argy/Beaver/Thorny can hold the resources with its weight and also not go over slot limit
While also keeping in mind that the games have weight reduction to items
I know that sounds like alot ... but it's a great idea ... can probably save alot of crazy blueprints and not just drop em thinking there is no way you can make it
