mutt for a long time.
But I found that every mail from Google Group can not show ascii_char to indicate threads (I subscribed some google groups).
I guess that Google Group is a newsgroup. So
mutt can not indicate with ascii_char.
If no ascii_char to indicate I can not find which one is for reply which thread.
So, I ask for a method for
mutt to solve this. Or, alternatively, suggest some clients to do this.
