I kind of wish this article was deeper on what benefits the OP was seeing from the plugins or what have you. I just was left hoping for something more from something that claimed to be a 'guide to the terminal' which usually is much more in depth to a particular workflow and you can usually glean one or two things you can add for yourself.

I'm from emacs land, and so generally using terminal over the emacs+GTK has a lot of limitations (ex: can't display or embed images, no drag and drop, copy and paste usually integrates better with the rest of the applications you are using when selecting regions of textual data). On top of that emacs comes with tiling for free where normally you would have to tmux+vim.
