Zellij 0.45.0: nested sessions, Kitty graphics, a fresh UI

Zellij 0.45.0 adds nested sessions, Kitty graphics, new UI

Zellij 0.45.0 introduces dedicated nested session handling, letting users run Zellij inside Zellij without doubled status bars or keybinding conflicts. It also implements the Kitty graphics protocol for rendering images in panes, adds a mobile web UI with touch controls, and redesigns the default interface with cleaner title frames and stacked lists. Other improvements include command-based scrolling, per-client tab sizes, and a focus-last-pane action.

Running Zellij inside Zellij has often been an awkward experience: doubled status bars, keybindings going to the wrong session and a lock mode dance to get anything done.

    Switched to Zellij a few years back mostly for the sane defaults, I expected to come crawling back to tmux, but it's actually stuck quite nicely and has become a staple in my workflow. It hasn't been a perfect experience, but I like it a lot and I'm happy to see a new feature-rich release like this.

    I'm curious for folks who use multiplexers: I've tried tmux and Zellij and if I used a multiplexer, it would be Zellij. However, I can't stand losing terminal real estate, but I don't know why that is. How do you deal with the loss of real estate from a multiplexer?

    I use Ghostty, so new tabs and splits don't feel that strange to me. I'm guessing the feature I'm missing out on is session resumption and presets? If I leaned into that more, then a multiplexer would be worth the potential drawbacks?

    Being cheeky here, but how many terminal emulators and multiplexers do we need?

    What is driving the Cambrian explosion of CLI tools in the last ~5 years?

    I’ve been using Linux since 2001 and use standard Konsole on zsh. I have a graphical desktop environment to deal with windows and showing pictures alongside them. Is it perhaps because I am an Emacs person that all I need exist within its loving embrace?

More from this day
