PetalDisconnect
by PetalCat
PetalDisconnect lets a player leave a Minecraft Java session instantly with a keybind, and can also disconnect when the game window loses focus.
What it does
The mod is a lightweight client-side utility for Fabric. It lets a player set how a disconnect happens, from a panic key that drops the connection at once to an automatic disconnect that fires when the game window loses focus. Its focus-loss check is meant to be smart: it decides when to disconnect and when to reconnect, so a brief alt-tab does not always end the session.
Auto reconnect is part of the same behavior, so a player can leave a server quickly and return without rejoining by hand. Every option is set in the mod's configuration, so the behavior can be tuned to each player's habits. Because it runs only on the client, servers need nothing installed to work with it.
Installation needs Fabric Loader 0.16.7 or newer and Fabric API. Mod Menu is optional and lets the settings be opened from the game's mod list. The files target Minecraft 1.21.10 only and are released under All rights reserved, so the code is not open source. Source code and an issue tracker are publicly linked.
