Hi BenSchorr,
Maybe you can provide a little translucency to the opacity that is the OneNote development team? Are these issues being actively discussed within the team, and if not is there a developmental plan in play? Do they have an MVP group?
Personally I've been using OneNote since the OG pre-alpha internal builds back in the day. I'm incredibly dismayed by it's lack of actual cross-platform development. Yes, I'm entirely discounting the OneNote for Windows 10 application, it's simply too limited when compared with my preferred OneNote 2016 app. It might as well have been developed by a completely different company with no insights into the earlier product usage.
I'm replacing my OneNote use with EverNote these days. That is a company focused on their users and providing true cross-platform equivalency and for me they're winning the game that was Microsoft's to lose.
