But the straw that broke my back with using kitty was, I'd end up encountering issues or trying to recreate some of iTerm2's features, only to end up time and again on kitty's maintainer's terse and dismissive comments.
e.g. IIRC his answer to "How do I set up tmux with kitty?" was something like "Don't, tmux is dumb" and closing it. Eventually I gave up.
