We all have had that... itch, that... urge. Imagine timed trials of ice boat racing. We already have the framework for it set up; it will be like parkour, but stages of ice boat courses that are timed. Maybe even a leaderboard if ya nasty.

Mod suggestion.

Shulker Box Tooltip.

ShulkerBoxToolTip tells you what resides inside your shulker box by hovering over it in your inventory. It is a wonderous tooltip that only allows for convenient play without any unfair advantages.
