I was personally really intrigued by the ambitions and design decisions in Xi, but it somehow lacked the one thing I can’t live without in a non-terminal editor - a tree view, at least when I first tried the OSX version. Perhaps that changed, but you’d think that would take higher feature precedence over something like collaborative editing right?
