Currently, Personal Space makes other users disappear from my view when they get too close to me, but they can still see me.
My suggestion is to make Personal Space mutual, not just one-sided: when someone enters my Personal Space, they should also stop seeing me while they remain too close.
This would make Personal Space feel like a real personal boundary, instead of only being a visual filter on my side. It would help prevent awkward or uncomfortable situations where people get extremely close, invade someone’s space, or touch someone just to bother them.
