Hello lunyBunny,
Yes you can use this for chests as well. Actually we had forgotten about chests :p, we’ll add chest model to pack. About Pick Up, our goal was to make this BP work without any changes to Character BP, just simply drag and drop (we managed it 
). But if we add Pick Up feature, users will have to make some changes to their Character BP. We might add it later depending on some… stuff… 
And thank you very much for nice words. It really means a lot to hear nice words about our first work
