That does make sense. You know I have a TV in my office that’s always off. You are right - with a nice long HDMI cable - I can use it for Youtube and LIVE F1 streaming. Especially since my GPU had 4 HDMI outputs.
Didn’t thnk about that, just because its a “TV” lol. But makes total sense.
Also, try terminator.
Alacrity is fast, but I prefer features. I would recommend Alacrity for a Raspberry Pi. 
Did you end up staying with Mate + i3? It’s worth a try? Your setup looks interesting, but I was holing out for Cosmic desktop from POP!_OS.
I did and actually like it. The tiling is nice and I find it very useful.
In my setup, I disable the MATE Desktop to get a closer vanilla i3 feel. I just wanted to avoid the hassle of printer setups extra. Looks like a MATE update came out, and the first thing I noticed is that Caja (file browser) has been tied in more to the desktop, so it no longer works for me.
I think I’ll be closely watching COSMIC as well, as I see it maintained in the arch AUR.
