I played a lot with Koikatsu and one of the element of the character maker was attaching random things to a char for new looks.talking about features, better IK for pose 2 would be nice too (like in blender, sfm etc.) maybe when you press grip, you move body while limbs stay in place (like with torso bone), and if you press grip and trigger you move everything like with root bone
The way it worked was simply select the element you wanted and move it around either by hand or by an X/Y/Z slider. I think this game would benefit greatly from having that function especially if we could have it selectively on whole body and body parts.
