Thanks. I'm interested in seeing examples (of Alacritty community not being nice). I'm aware of one now [1] but I have not been involved with the Alacritty community much. I read/write a few bug reports when the project was born; after that it has served me very well (compared to iTerm2 and Terminal.app). IIRC there was something with ligatures but I don't remember.
Thus far I have not been able to get my italic bold font (Cartograph CF) working on Ghostty, but this is a minor issue.
