Make tmux pretty and usable (2024)

Original Article ↗ Hacker News Discussion ↗

Terminal users trade tips on making tmux more usable and visually appealing, from remapping awkward default keybindings and enabling mouse support to theming the status bar and integrating with editors like Vim and Neovim. Many praise tmux for session persistence and ubiquity on remote servers, but complain about its scrollback and copy‑paste ergonomics, prompting some to adopt alternatives such as Zellij, byobu, kitty, or wezterm, or to rely on tmux frontends like iTerm2’s control mode. A recurring theme is the tension between deeply customizing tmux for comfort and sticking close to defaults so skills transfer cleanly to unfamiliar machines.

Overall Themes

  • Tmux is widely seen as powerful but unfriendly by default: great once tuned, awkward out of the box.
  • The thread centers on usability (keys, scrollback, copy/paste), theming, and whether tmux is still the right tool versus newer multiplexers or smarter terminals.

Tmux vs Alternatives (Zellij, screen, native terminals)

  • Many switched from tmux to Zellij, praising its default UX, pane/tab handling, mouse support, and vim-like keybindings.
  • Others returned to tmux due to Zellij crashes, missing features (e.g., status bar toggling, window previews), or its stance against tmux-style keyboard copy/multiple buffers.
  • Screen is mentioned as smaller and long-proven; tmux offers better UTF-8 and saner defaults, but screen remains attractive on very constrained systems.
  • Some argue modern terminals (kitty, Wezterm, KDE Konsole) with built-in tabs/panes and scripting can replace tmux entirely.
  • Size matters on embedded devices: Rust-based tools like Zellij are criticized for large static binaries.

Core Use Cases & Session Persistence

  • Main tmux use: detaching/reattaching SSH sessions, working on headless VMs, and surviving flaky connections or mobile devices.
  • Some want only persistence, not panes/tabs; lighter tools suggested: dtach, abduco, shpool, zmx, mosh, etc.
  • Others integrate tmux tightly with editors/IDEs (vim/neovim, Emacs) and use project “sessionizer” scripts, fzf switching, or byobu.

Customization, Keybindings, and UX

  • Frequent rebinding of the prefix (Ctrl‑a, Ctrl‑Space, Ctrl‑s, Ctrl‑z, backtick) and pane navigation to vim-style keys.
  • Some warn against heavy customization because it breaks muscle memory on stock servers; others maintain dotfiles or scripts to deploy configs quickly.
  • Control mode (-CC) with terminals like iTerm2 is praised for making tmux panes look and behave like native tabs, though the protocol is called ugly and support is limited.

Scrollback, Copy/Paste, and Mouse

  • Many complaints about tmux scrollback and copy, especially with mouse mode, browser terminals, macOS Terminal, and OSC52 issues.
  • Workarounds: vi-style copy-mode, custom keybindings, mouse-on configs, plugins (for fuzzy extraction or hint-based copying), and mapping system clipboards.
  • Zellij is criticized for lacking robust keyboard-based copy and multiple buffers, which is a dealbreaker for heavy keyboard users.

Aesthetics & Theming

  • Default bright-green status bar is widely disliked; users apply themes, powerline-style bars, color-coded hosts/root, or hide the bar entirely.
  • Some view prettification as nice but secondary; others say tmux only becomes “usable” after substantial theming and config.
