Crouch-Jump is a customizable Spigot 1.16.5 plugin that temporarily gives players Jump Boost when they crouch. It works on versions Release 1.1 and above.
FEATURES
The time window that allows players to crouch-jump can be easily edited
The jump boost amplifier that's applied to players when they crouch can be easily edited
Effect stacking allows players that already have the jump boost status effect to crouch-jump even higher
Crouch-jumping can be locked behind permissions
Vast version support - this plugin is so simple to the point where it'll (probably) work with every version past Release 1.0
