When a person tells another person "you need to do X" or "I did Y and it didn't work on my machine", they sometimes ignore important details due to their own curse of knowledge. That's when I need a shared terminal/editor so that both parties know exactly what is happening.

I don't frequently share terminal/editor but occasionally need to do so, maybe a handful times a year. Most of times when I tell a new colleague "hey, connect to my tmux socket by running this command / opening this link", they were amazed and thought it was magical. I am not a Zed user but it's always welcome to see people making effort to make pair programming easier for everyone.

Now, I don't know how I would feel if one day my colleague send me a sharing session link that can only be opened by a particular editor.
