It would be hard to convince me to move away from iterm2. But a theme for it would get massive adoption.
I moved to ghostty from iterm2 more than a year ago. At first, I thought I will be missing the iterm2’s flexibility and config options, yet in reality, I never even looked back.
I moved from iTerm2 to ghosttty / wezterm (for a bit). Moved due to the AI inclusions (despite them being moved). I've had no issues, in fact, I prefer ghostty to iTerm2 now.
