Which terminal window app allows for multiple panes and click to open new window I am watching this screencast series where the guy is using OSX and has this cool terminal window client.

Trying to figure out which one he is using.  Here is a screenshot:



It looks like he is able to also click on folders and it opens a new terminal window.  Full video is here: https://youtu.be/-kXYycFYDzo?list=PL05JrBw4t0KqoFUiX42JG7BAc7pipMBAy&amp;t=211

Can someone recommend software that performs this based on the screen shot?
Acme in Plan9.

There's a macOS version available.

If you want this video Ori actually talks through and explains how to change and edit how the editor behaves: Plan 9: Not dead, Just Resting, by Ori Bernstein
