The mod (latest version 1.19.3) and a hack client (Future) Both have an Entity Outliner, allowing you to see which mob exactly is behind a wall, because it outlines their body rather than draw a box around the mob, with Entity Outliner mod giving you the option of colors as well.
I feel like having this in Wurst would be a great Quality upgrade, and would be really useful!
P.S. The Entity Outliner mod dev has a free open source of the mod on github, so we could implement that in wurst easier(hopefully!)
