Often times, when I'm done a task, I'd like to close out of all buffers I was using for it. However, I usually don't, because I think it'd be a pain.
What I'd like is to be able to kill all buffers spawned from a particular one -- usually, when I begin a task, there is a buffer I open first, and I'd like to be able to kill all buffers spawned from that one -- all buffers opened with
C-x C-f or whatever while I was initially in that buffer, or recursively. Does this exist?
