Microsoft are more open to feedback than ever before. Two areas I think are worth giving your feedback on are:
Storing email signatures in the Exchange mailbox
I’ve been chasing for this for a long while too:
LOL, this tweet was 9 years ago, almost to the day!

Keep OneNote Desktop App in Office 2019
Update 22nd April 2018, Microsoft has confirmed Onenote Desktop “2016” can be installed alongside Office 2019: “OneNote for Windows 10 will replace OneNote 2016 as the default OneNote experience for both Office 365 and Office 2019. If you currently use OneNote 2016, you won’t notice any changes when you update to Office 2019. We’ll continue to offer support, bug fixes, and security updates for OneNote 2016 for the duration of the Office 2016 support lifecycle, which runs through October 2020 for mainstream support and October 2025 for extended support” https://onenote.uservoice.com/forums/327186-onenote-for-windows-windows-phone/suggestions/32737648-include-onenote-for-desktop-in-office-2019?tracking_code=7bb3fc131b6f7be238ef5091aabb7385
It sounds like Microsoft plan not to ship OneNote 2019 desktop in Office 2019 (which will only ship as click to run). The apparent logic is OneNote is free now anyway and you can download the app for free. I’d guess Microsoft will mainly push the UWP version, but the MSI version is available for free too. However, lots of IT shops will rollout Office 2019 but lock down installing other apps, what if you have Office 2016 Click to Run today and tomorrow get Office 2019 from IT without OneNote?
This doesn’t seem like a great move to me, if you think the same you can vote here: https://onenote.uservoice.com/forums/327186-onenote-for-windows-windows-phone/suggestions/32737648-include-onenote-for-desktop-in-office-2019
