It's no different from what we do with `*Help*', except that yes, I meant saving the buffers (output), not automatically reevaluating the sexps. As I said: "useful to revisit previous evaluation results". Your criticism in that case is that this would be "unusual"? Not for someone who uses *Pp Eval Output* a lot. This is similar to requests for saving *grep* buffers etc. The other possibility to consider is simply providing undo, so you can go backward to previous results (and forward again). That would less handy than separate buffers with navigation, but it would be better than nothing. > So I don't think this sounds like a very useful feature. Closing.
