TunnelESP

[GekkeHans]

Detects 1 by 2 tunnels, handy for finding tunnels in the nether when looking for bases.

You can use esp for wither skulls

There isn't an easy way to tell if a chunk has been modified by a player due to different chunk versions and not knowing the seed on most servers.

I meant with wither skull tracer that it draws a line on the path it went.

[GekkeHans]

essentially showing where the wither that shot the skull is

[5HT2]

That wouldn't be accurate as how minecraft determines the paths for those is nearly random and if the wither moves after shooting it, and is in an unloaded chunk, it wouldn't be possible

[5HT2]

I don't see a feasible and performance efficient way for this, leaving it as unplanned unless someone has some ideas.
