Jules Hedges (Jun 15 2020 at 15:20):@David Tanzer Am I an idiot, or is there no way to preview an edit besides committing it?
David Tanzer (Jun 15 2020 at 17:48):@Jules Hedges Yes. you observed correctly. As a workaround, I created a page called "preview", which anyone can use to test things out. (One can also work in the notebook web.) Anyone feel free to replace the entire contents of preview for their own testing.
David Tanzer (Jun 15 2020 at 17:54):If you think it's worth pursuing, you can add it to the page for bugs and feature requests.
David Tanzer (Jun 15 2020 at 18:40):Note also that repeated saves within a certain time window don't create separate versions in the history. So by repeated saves and viewings, you end up with just one version for each editing session.
