While trying to figure out how I could build a custom auto-crafting system with Integrated Dynamics, I realized that having a List Proxy that could store a list of recipe variables would be really handy. I'd love to be able to add/remove variables from the list without having to rewrite a variable.

Also, I haven't yet checked if proxy/materializers can be used by pipes/item tunnels, but that would be great too.

Could you clarify what you mean with a short example? Because I'm not entirely sure what you mean.
As recipe variables don't exist atm, or are you requesting that as well?

Nah, you don't need recipe variables, List of Items works just fine.

So, it would work like a proxy, in that you can create variables that refer to the List Proxy Block and indirectly to the variables inside it. You could then add/remove variables from the inventory, and the values of those variables would appear in the list.

Ah ok, now I understand.
Good idea!
Shouldn't be too hard to implement.
Can't say when I'll be able to do it though.
