Swipe action and hold
When performing a swipe action and holding on it mid the swipe, that action can be automatically assigned to future messages from same sender or same conversation. Similar to what mailbox had.
Yes please!! I love the now defunct mailbox app function that auto Selects actions using slide and hold.
I want this function badly. I loved the now defunct Dropbox's Mailbox app because it had this function thst automates action on every received email from a particular email address.
That's a pretty frickin brilliant idea.
