I would like to see disabling the display of mobs ' lags (all). More precisely, the graphical display itself is in the world, and not in the list for ordinary players.
According to the lags, you can see mobs through the blocks, this is a small problem for server rules.

I will implement this in the LagGoggles rewrite, I am currently developing the environment that I can port over from the old version (The one I am rapidly committing to right now) to the rewrite (Currently in a private repository until finished)
