Space efficiency... hm i guess its about time yeah. Though im not too concerned about crafting items, the armoury space could use an upgrade which im glad they did. Funny you should mention the grade 1, 2, 3, stuff. Reminds me about back in 1.0 We had HQ's ranging from HQ+1, HQ+2, HQ+3. Every damn craftable item, without the option to downgrade them. I guess due to that, to this day, i consider the HQ downgrade option the best thing every in the game >.>
