Noticed this while doing Botany/Mining, and it's great having it display the amount you already have in your inventory when you select it... I just wish it would count the HQ versions as well, separately of course (so Total: X, HQ: Y).
Would save me the trouble of checking my inventory before I finish up (I loath leaving with what will end up as spare parts) or keeping a mental count when I'm switching off my brain during Botany/Mining.
