Bluebird

A minecraft mod that allows you to edit more F3 settings such as hiding targeted block tags. This is a somewhat updated version of CleanF3.

Shows a shield icon when a player is blocking with a shield and an attack with an axe would disable it. Also has a crosshair indicator enabled by default

Obfuscates / hides death messages and kill messages that invisible players get. Both default to true but can be edited through gamerule commands.
