Tried Kitty for a few months. Didn't like the developer's attitude when people raised concerns and asked for "tabs". He said "just go use tmux on top of Kitty." I use tmux sometimes, but the idea that you have to glue together several pieces of software (each of which can break at any point) just to get basic functionality (like tabs that some people want) is insane.

I stopped using Kitty and switched over to iTerm2 and have been happy ever since. Most importantly, it allows me to set a custom keyboard shortcut to summon my terminal any time on macOS.
