Currently with the limitation of how Get Ingredients works (with only 3 items, not a loop, and just generally a weird implementation), using the signal register of the construction site *almost* works perfectly. It shows me only what items are needed, and updates as soon as one of those items gets filled.
The problem is that this doesn't update until the item is actually filled.
Pretty simple behavior here that I'm going for. Check all construction sites via my command center. I don't really care about resources, but if it needs components, I want to see if I've got one, if not, build it, then send it along to the construction site.
I can picture that this might be something that's not very user friendly for new players and it might eventually warrant something more specific, but as of right now, it's almost workable. The only thing that keeps it from being a perfect workaround is that when I issue the transfer order, because construction sites aren't normal inventories, it doesn't reserve the item, so it doesn't update the signal register until the item is received, making a clean and elegant solution here impossible. Yeah, I can just wait for a bit and hope it's been delivered, but if the signal could update as soon as the item is requested and on its way, that would be perfect.
