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.

Shows the visual cooldown when it gets silently reset. Visualizes MC-118740

See barriers with the press of a key. There is no registry mismatch meaning you can use it in singleplayer without others needing the mod
