I would like the ability to set default fonts that align to the fonts available in Office365 tools for a more uniform experience. Where all the O365 apps are defaulting to a nice Aptos Display font OneNote is on an Island referencing system fonts. Would also aid in ensuring you are using proper branding where companies have rules around format and font.
Many users also complain about how OneNote "decides" to change fonts and font sizes in the middle of lists or bullets seemingly at random which makes for a friction-filled experience while trying to use it for taking... notes. It is nice they are going to Copilot for handwriting recognition, but that seems more like a nice-to-have if I am ever using OneNote on some kind of tablet which is likely an outlier for most use cases - fix the core capabilities of the tool before running off to add new features. The marching orders at MS is everything Copilot so different groups have to invent those value propositions - I get it.
When porting notes from Teams or Outlook into OneNote the format of the meeting header information is not very intuitive:
Where most would like to see the meeting subject, data, location, link to Outlook Item, followed by Participants, and the last item - the "Invitation Message" that likely contains the agenda or the meeting framework. Instead the "Invitation Message" is sandwiched in a no-man's land between the Participants and the Link to Outlook Item. Would make more sense to have the Invitation Message last, after the Participants followed by Notes (if the word "Notes" is even needed - usually a static font that is too large that I always delete as my agenda is usually in the message body and I start there.
Syncing can still be a bit rough across different platforms which seems a bit archaic with cloud data and mobile/broadband transmission rates these days, like you are caching and synching local DBs. It would be nice if Sharing could be done at the section level too - not just at the notebook level. (perhaps you can, but it does not appear to be straight-forward). I have worked around this by making some sections password protected to parse access of sections that I want to organize under one Notebook.
