Once you really know your keyboard, it's like an extension of your hands. You can fly through those six terminals, and moving your hand to grab a mouse means stopping whatever you were doing. That wall of text is all familiar to me - I see an UI full of empty space and wonder what I could have used it for.

Of course there are great reasons for using pointers also. I'd say this is mostly a preference, I'm sure you are extremely effective using your own methods. I have maybe two dozen terminals open atm, and I can tell you what each of them is for - but put a phone bill or a bank statement in front of me and it might as well be Greek.

At first glance it looks like an electron app, so thats probably a great reason not to use it. (But I could be wrong)

I just use Zed and interface to agents via ACP. Works like a charm.
