Aeronautics:Gravity Visualization

A Create Aeronautics add-on | Minecraft 1.21.1 / NeoForge

One jar, three sub-mods:

Gravity Visualization — See and tune your center of gravity. Right-click a contraption with the Spark Wand to overlay per-block mass and the center of mass; counterweight blocks adjust mass and buoyancy by hand or redstone, so balancing is no longer guesswork.

Simplification Related — Hassle-free machinery. An analog transmission that turns a 0–15 redstone signal into a fixed RPM; a portable engine with 15 speed settings; a programmable sequential feeder for sequenced assembly lines.

Starlight Logistics — Logistics made simple (of packages, and... people). World anchors ship packages between any two points; addressing signs switch target addresses in one click; activated ender pearls can be packed into packages that burst open on arrival and teleport the player — across dimensions, too.

Every feature is independently toggleable on the in-game config screen (all on by default); disabling one removes its recipes and acquisition paths.
