Those videos seem completely pointless.

I use bash, and can customise my prompt to show my current working directory, and the current github branch - and it's trivial to do.

I use screen a lot, and I can flick between different screen windows to do any task required just as easily and he can. It also, I believe supports split panes, but I haven't found the need to use them myself yet, as I use iTerm2 which is perfectly fine for that in itself.
