oh my god, the .tar.gz is 90MB compressed, uncompressed its 265MB. The xterm source code is 7-8MB. We dont need a terminal 33 times the size of a basic terminal.

While I entertain the idea of a terminal in a web browser, I dont believe it has the ability to capture the keyboard entirely for tmux, emacs, etc to work. I also think the use of a web based terminal is quite limited to specific scenarios. Perhaps it would be nice to connect to a k8s cluster on a remote machine.

Seriously though, I've got a potential use-case where I want to cobble together a few related scripts into an an ad-hoc REPL that supports HTML and image output. A key library I have to use is written in JS.

Granted, this is my first time seeing Tabby so I'm not sure if it will work - just that I might see a use for it.

I agree with your sentiment 100% though - this is way too heavy for a day-to-day shell.
