If you're going to remove OneNote from Office 2019 and recommend people use the less full featured OneNote UWP app...you need to add pageTemplates from OneNote 2016/365 to the UWP app.

All functionality for Page Templates,
Creating a template
Saving a template
Using a Template as default for a note section

I really like the desktop lay-out with notebooks on the left, sections on top and pages on the right. I tried the UWP version, and while perfectly suited for use on a tablet (with a reduced number of - bigger - buttons), I feel it misses too many features to replace the desktop version.

So please include OneNote in the new Office 2019 suite!

For all the OneNote desktop user since the beginning.
It is important that all the local OneNote-files can be used in the future without an upload to OneDrive.

Integrate tasks and tags across OneNote, Outlook (desktop/web/app), Windows 10 mail/cal, and Microdoft To-Do app.

1. I'd like existing OneNote 2016 & 2010 feature "Insert Outlook Task" be included in OneNote for Windows 10
2. I'd like OneNote Linked tasks be available at my Android mobile device.

One of the most powerful feature is the ability to tag things as Outlook Tasks. Also the ability to create a OneNote page from a meeting. These features are the heart and soul of OneNote.

Please add page sizes so we have the option for the pages to look like microsoft word in a way but in one note so that i know how much i can fit in one page in order to print it out and study from my notes

Outlook allows me to "copy" an e-mail via "Send to OneNote" into a page. This is only working with the OneNote 2016 desktop app. It would be great if I could send an e-mail to the UWP OneNote app.

A 'store' for templates where people could post and search for templates to download.

I want to be able to create lists and arrange them and prioritize the actions with a drag and drop capability. It would be nice to see if Microsoft could incorporate it's To-Do app into OneNote or build a similar functionality natively into OneNote. Priorities change constantly and giving the user the ability to arrange items on a list with drag and drop rather than cut and paste would be so much more helpful.

I would like the video recording feature to be returned! I need to be able to continue recording videos into my OneNote. Not linking---recording directly from OneNote.

It would be really helpful if you could rotate inserted PDFs in OneNote. Currently, the "Rotate" button is grayed out.

The current options are either unlimited width & height or fixed with & height.
Can we have an option of fixed width and unlimited height.

Use case: Create notes that can be printed without affecting the size.

It would be amazing if you could add a transparency option to the pen selection.
This way it would function exactly like an Highlighter but it would have a rounded edge, much neater than the highlight version and way easier to manipulate when used to fill and outline things!

In alternative, just add the option to choose different highlight shapes!

Please, Please make sure the OneNote app has the desktop OneNote functionality to assign outlook tasks, tags, and a developer API for developers like Onetastic!

Make it possible to add hyperlinks to drawing objects.

You can't possibly be serious??? How can you not have a replace text function in OneNote??? This is crazy!!!

Please add this function ASAP

Please implement the 1.1, 1.1.1, 1.1.2 format for number lists. This is the most common list style I use in Word (for content pages etc.) and I don't understand why it is not available in OneNote.
