Oh man! I hope I haven't been teasing you too much and now you won't tell me all your brilliant ideas! If so, I apologize; it's just sort of my nature and my sense of humor. I
*LOVE* hearing your ideas!
(Even the crummy ones!

JUST KIDDING!!! See, there I go again. Can't help myself...)
The BOM tells you everything required to make something, not everything you need to get/make to make something. Actual example I noted down:
required to make 4 gates:
8 silicon crystals, 6 iron ingots, 12 copper bar.
What it doesn't say is that I needed 19 bobs of clay and 7 charcoal to make the 8 silicon crystals. And to make the 7 charcoal I needed 21 woods. So the list is actually:
8 silicon crystals (19 bobs of clay, 7 charcoal (21 woods)), 6 iron ingots, 12 copper bars.
NOTE: The BOM only tells you what you need to make 1 set of something; it doesn't account for you wanting to make 10 of them (or whatever number). You have to do your own multiplication.
But I think you're looking at the SHORT list, which is what you're short. The whole *point* of the BOM is to reduce the recipe to raw materials (clay, wood, etc.)
SHORTCUT: if something is in your short list, you can tap it and that becomes the selected item (as if you wanted to craft one of those). If you still have short items, you can tap that and repeat. The problem (?!) is that, after a few of those taps, I forget what I was trying to make in the first place.
So maybe the SHORT list needs a BOM toggle. Ooo, that'd be pretty cool -- it could do the multiplication, include missing tools and generally just show me "before you can craft a plastic-seed, you may's well gather up this much raw materials..." (I'm currently working on my GMO-2, for which I need a GMO-1, which requires more steel than I have, which requires silicon & iron. So I plant silicon & iron. An hour later ... wait, what was I trying to make, again?!)

Yeah, that's the cool UI -- Short-list toggle to show your short-BOM -- right?
NOTE: Here's BOM for AND gates (2 per crafting), showing clay, etc.:
