Inventory Stopwatch Mod
by AgnesTachyon
Inventory Stopwatch is a client-side Fabric utility that times how long each inventory visit lasts, from the moment the inventory opens to the moment it closes.
What it does
Once installed, the timer starts when a player opens the inventory and stops when it closes, reporting the exact duration in milliseconds. Each measurement is placed on a built-in tier scale, from Too Slow up to legendary, so a player sees immediately where a refill or inventory change falls. Session statistics record the total number of inventory opens and the average time per session.
The mod is aimed at competitive players, kit-peddlers and anyone practicing high-tier combat who wants to see how much time inventory management takes. Settings can be changed through the Mod Menu integration, which lets a player switch chat messages on or off, hide the session averages and reset the statistics, or through the invstopwatch commands. It requires Fabric API and Cloth Config, and the Mod Menu integration needs Mod Menu installed.
The mod is client-side only, so a server does not need it and players can join a server without installing it. Files are published for Fabric alone, with the 1.0.1-release build for 1.21.11 as the current version, released under the MIT License. The code is not open source.
