    Project mention: State of Terminal Emulators in 2025: The Errant Champions | news.ycombinator.com | 2025-11-03

    I run Kitty and use this feature regularly. Most of the time, I rely on it within Yazi [1], a TUI file manager, but I can also display plots within the Julia REPL, thanks to the KittyTerminalImages.jl package [2]. It's even more crucial when I'm navigating a remote directory and need to check an image file, as I usually have timg [3] installed on those servers. Once you discover how valuable this is, it becomes a permanent part of your workflow.
