Thank you for the very thoughtful comment. The required login I think is enough to scare me off. Which is a shame. It’s the first time I’ve heard of this terminal and the features listed intrigue me enough to want to explore more.
A lot of Mac users either don't know they're using zsh by default now or simply don't take advantage of it's scripting language/featureset. For those people, I think fish makes a compelling upgrade. No log-in, just a slightly nicer interactive terminal prompt.
Warp team: I watched the demo and it looks great, and I downloaded it while going through this thread. I didn't install. I think you're boxing yourselves out.
