Recently I’ve been seeing a new screen that I never noticed before. When I open K9 Mail, it seems to list all the new emails I’ve got in all of my folders. I find that pretty convenient, but if I close that folder I cannot find a way to access it again. Is there a way to do that?
The screen lists “new” messages, i.e. messages for which the app has created a notification. You can only reach it by tapping the (collapsed) notification grouping all new message notifications. Once you’ve opened the screen, the notifications are removed and the messages are no longer considered new. So even if there was another way to get to that screen, it wouldn’t display the same messages again.
