I have been using EN user for approx 10 years and have established some habits based on the functionality I experienced from my "early days".
First it was possible to have multiple accounts in the same window. Easily choosen from the left panel in the win app. Drag and drop within the same app window.
Than for a few years ago they separated the accounts, but made it possible to have two accounts in different windows "up" at the same time. Pushing real estate of the screen - espesially when using a laptop with just one screen available. But still functional for my use.
When v10 appeared I tried it for some days - found it hopeless and switched back to legacy (v6.xx).
Now I'm seriously wondering what to do. Clearly this has to implicate some change on my side. Most probable I'm converting my business notes (premium) to OneNote 365 since we already have the Office 365 package onboard. For private notes (free - but still private business related stuff) I would probably stay with EN.
EN simply doesn't support my working process anymore....🤔
