I haven't heard of Ghostty before today. I'm reading the docs; but what are the main selling points?

Personally, I've used Terminal.app (for a bit), iTerm (for a long while), Konsole (in the past, on Linux) and more recently I standardized on Alacritty (macOS) and Kitty (Linux). GPU acceleration puts it in the same general bin as my current toolchain, but your comment alludes to it pulling in some concepts from iTerm, possibly -- is that the case?
