Kitty is probably the best terminal emulator I've ever tried out... It even made me drop Tmux as multiplexer on my stupid Mac !
I only have basic use case right now, nothing complex but customization seems way above others.
The full OSC52 integration with micro for copy/past over SSH and taking up the terminal clipboard was also a game changer (nearly dropped micro because of this...)
I only scratched the surface and have only basic usage and still I can't believe one single person is behind this project (I think?).
