Child Function For Items?

[operatort]

Hey i wanted to ask
Why can I give items a parent item?
Is that meant for Item
Parent Computer (1x)
Child RAM Stick (4x) ?

I tried to abuse it for Categories
IE Parent: Ball Children: Basketball, Football, Tennisball
Unfortunatly that doesn't work as good.
But Maybe Categories are a good idea, you could also use it sum-up the number of items and their values

Quite a rabbit hole of possible functions.
So far I do like your implementation the most :)
