I use OneNote for Mac v. 16.32 on my MacBook running OS Mojave 10.14.6. The lack of an option to set page size (a là page setup in other msft products makes) makes sharing files via printout or PDF a real hassle. Even if I create an arbitrary background box to constrain the size of my notes/images, which is a nuisance already, the title still extends beyond the width of a single letter or legal page. As a result, content that carries across page-widths is lost or distorted.

Please add an option to define page width, or at least to scale pages to letter width. It would be EXTREMELY helpful!

Ability to post export a note in markdown - ie as a *.md file. Recognise that some features may be lost in this process. But links back to OneNote could be maintained (an option in the export process). It would be great if tables could be exported as mardown tables as part of this process. The use case for me is preparing documentation for posting onto GitHub - OneNote is great for gathering and composing the information, but it's a bit of a faff getting it from there into GitHub. Given that Microsoft own both OneNote and GitHub it would be good to see tighter integration between them!

The OneNote Notebook Importer tool (link at: https://support.office.com/en-ie/article/export-and-import-onenote-notebooks-a4b60da5-8f33-464e-b1ba-b95ce540f309) does NOT WORK on an update Mac (OS 10.14.5) and OneNote (16.27). Notebooks can be exported by following the advice on this page, but the exported notebooks cannot be imported (directly) back into a Mac. After much difficulty (MS phone advisers!) and some assistance (some responses to questions on MS Community), I have found that is only possible to import the exported Notebooks on a Windows PC. It doesn't work on a Mac, despite what is said on MS guidance page (link above, which needs to be corrected and currently wrong for Mac users). There is more information and screen shots showing the problem on MS Community in questions raised on:
• How import exported OneNote notebook, folder or file?
• Why is Microsoft guidance on import and export from OneNote on a Mac wrong? Why are Mac users of OneNote so poorly supported?
Please put this right and sort out the Importer Tool so it works for Mac Users. I'd suggest looking for a better method too, as using an online importer to restore a back-up does not look best way to go and I feel there should be a better option.
