Add items pools checklist.

[KiII-ReaI]

I want to see how much stuff I still can get from cores, how much in shop, how much from cargo creates, how much from lost gear and lastly, but not the least, Bosco. At the moment the DRG Completionist does not include that stuff. like victory moves, cosmetic cores. You can leave out DLC, as they are pretty obvious. Simple checklist would be great.
