Its early GitHub releases moved from v0.1.0 in April 2020 to v1.0.0 in May 2020 and v1.1.0 in March 2021. ### Adoption history The package-manager footprint is small but real: the input facts list Homebrew, MacPorts, and Nix packages, while the README also documents installation from Go source. ### How it is used 3mux is used from the terminal to split panes, move between panes with i3- or vim-like keybindings, search scrollback, resize panes, and manage sessions without a large tmux configuration. ### Why package nerds care Its package-nerd appeal is as a compact terminal-multiplexer alternative: a single Go CLI that packages familiar tiling-window-manager ideas for shell sessions. ### Timeline - 2019: GitHub repository created. - 2020: v0.1.0 release published. - 2020: v1.0.0 release published. - 2021: v1.1.0 release published. ### Related projects - The README explicitly frames 3mux against tmux and borrows interaction ideas from i3. ### Sources - - - - input source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
