VR tracking - finger/leg/eye - fullbody tracking

Hello, it would be neat if there would be integration of things like, eye tracking, finger tracking, and full body tracking for the people that have it, i don't have a couple of those myself, but it'd add more immersion to the game, though i always do hope that people with leg trackers don't just sit and play with them on myself unless there is a way to make them stand or actually sit in the game, don't really wanna see people floating around unless they get a hover chair or something under them if they do that lol
