There seems to be indecision and lack of direction when it comes to OneNote. Are there two different teams developing it? Has development stalled?

There are several features in OneNote 2016 that are not available in the Windows 10 UWA version. The most major one being the ability to searching image text converted by OCR. Please decide which product you want to succeed.

I personally have tried using the Windows 10 version for several months and had to abandon it in favor of the 2016 version.

I HATE the layout of the new navigation manu in the latest update of OneNote app for Windows 10, in this model, you can't customize the menu position, etc while you could in the previous versions. I don't understand why you think you need to change what's good while you do not touch what's bad! Please give us the previous navigation layout. It had no problem.

The ability to export single pages, sections and entire notebooks into a pdf file is a really helpful tool, that is missed by many users.

Please include this into the windows 10 version!

OneNote 2016 was easier to navigate with the Section Tabs at the top instead of on the side. Please add an option to adjust the location of the Sections tabs.

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.

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!

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

The most popular post that mentioned this was in 2014 and it still is not fixed, so I thought it was worth suggesting again. This seems to be a very basic functionality of a table on any computer program.

Need to continue to have all Outlook integration functionality in Onenote for Windows (particularly task creation) if you are going to sunset Outlook 2016. Difficult to understand how it could be a good business decision to do otherwise.

In onenote 2016 you could click a button in the outlook meeting, all meeting information opened in a new note and if you used Skype for business in tracked attendance. It was brilliant. Now as 2016 is deprecated we corporate users are losing this great productivity feature. Please please revive it

The infinite paper size being the only option forces me to keep using OneNote 2016 or a simple pdf editor instead of OneNote for Windows 10. It is impossible to export anything from OneNote if I cannot tell where the page ends--it always will format horribly.

Windows 10 "Metro" "Windows Store" OneNote App is Awful, kill it and bring back OneNote 2016.

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.

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

By default there is no way to see if your written notes exceed one page. You have to write very small or adjust the whole text to fit into a page so I can print it out.
I would appreciate a feature like in Excel where you simply can tick a box an you can see where the border of a page is.

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

It would be so helpful if I could add reminders for tasks in onenote directly (kinda like how Evernote allows you to). I love that is done through the app so it truly pops up on my screen reminding me that I have a task to do.

OneNote 2016 has the advanced option "Lock password protected sections after I have not worked in them for the following amount of time". Such an option does not seem to exist in OneNote for Windows 10. The features of OneNote for Windows 10 have improved a lot over the past year or so, but having to reenter the password after only 5 or 10 minutes of inactivity is annoying and is the one thing keeping me from switching from OneNote 2016. Please add this feature to OneNote for Windows 10.
