CVTweaks

Among its client features, a fly speed changer lets a player raise or lower creative flight speed with plus and minus keys, and pressing both resets it to the default. An autohome option can set a home automatically in survival worlds when health runs low, and a back command returns a player to the spot where they died. A warp menu opens with the H key in creative worlds and lets a player type a username or plot to jump there quickly.

Chat handling is covered by a channel toggle, which turns global or group chat off and lets a player send messages without typing the channel prefix first. A nearest drop command reports the closest warpable location by coordinates. RegionScript 2 runs custom Lua scripts on the client inside a sandboxed environment, loaded from Pastebin, and a script's tick function runs 20 times per second with access to player data through the player table.

CVTweaks is open source under the GNU General Public License v3.0 only. The mod is published for Fabric alone, with one file for 1.21.8, and it is client-side only, so servers need nothing installed. Its source code and issue tracker are public. The author describes the project as an unofficial, player-made mod that Cubeville endorses.
