• alacritty
• neovim
• tmux
• vifm - terminal file manager with vi keybindings.
• zathura - pdf reader with vi keybindings.
• inxi - prints information about your hardware.
• tldr - cheat sheet for common commands
• qalculate - the most powerful calculator I’ve seen. There are qt, gtk and cli versions of it.
• moreutils - collection of tools. My favourite is vidir, it opens directory structure in your terminal text editor, so that you can rename multiple files easily.
