Yeah, he is... a character, to say the least. It's a shame because outside of Konsole, Kitty is the closest thing to iTerm in the linux space. what's holding it back from being as powerful and usable is basically not having a UI at all, and he's opposed to having more GUI at all, like on this very basic feature: https://github.com/kovidgoyal/kitty/issues/1402
Have you tried Konsole, the KDE terminal. It is absolutely terrific. It handles RTL and multibyte characters perfectly, works with tmux, has monitoring for both activity and silence, renamable tabs, horizontal and vertical splitting, bookmarks, scrolling, colour support, on-the-fly font resizing and colour scheme switching, keyboard shortcuts that do not conflict with any *sh, copy and paste shortcuts for both the normal clipboard and the X11 clipboard, supports the mouse, search functionality, I could probably go on. If iTerm has any feature that I'm missing, I'd love to hear about it.
