That’s what I’d always do. On more complex notebooks, though, is it possible that isn’t a solution? I wouldn’t think so but I am happy to be surprised. Then again I use notebooks only at the end of a project to present work in “executable presentation” style. Restart and Rerun all has been always been sufficient for me. More generally, I took a look at notebooks, thought, “Why develop with all the extra baggage” and left it at that until ready to experiment with presentation methods for (tight) core ideas.
