Absolutely a great idea, especially since it’s in the desktop version. Having PC issues today and really miss that functionality.
This is a feature in Outlook, so it should be easy enough to accomplish in the app. Many, many people use multiple folders.
It would be better if I got notified for all folders, not just the inbox. Maybe I’m missing something, but I can not find it. Only notified for the inbox.
I use several folders to sort emails when they arrive and I can see and retrieve emails in them all. It would be better if I did not have to manually go to each mail folder in order to see if I had mail and to update it. Also, I think I am only notified when emails arrive in the "Inbox", but not the other folders.
