The Problem
I have a lot of folders and as the Mailspring doesn’t support saving filters or smart folders I have to manually go through all subfolders with unread items. It’s very uncomfortable.
Proposed Solution
I propose to add the button (with hotkey of course) “Next unread” which should open the next unread item even it is in another folder.
Alternative Solutions
I didn’t find any alternative.
