I was going to mention the same thing. I liked the old Pop Shell and have now been experimenting with the new tiling interface.

Off topic, but System76 really seems like a great company. I enjoy my Linux laptop and their software support is good. I am stuck on Apple's platform for the Apple Watch and iPhone (and I like iPads), but I wonder if I would ever buy another Mac laptop. Turnkey Linux systems, like those of System76, Dell, etc. really make using Linux low overhead.
