• Youtube's Save to Watch Later in notifications
• gboards swipe left from backspace to delete words
• gboards clipboards (but found Clipboard app as alternative)
• swipe down from home screen to show notifications (i'm using AssistiveTouch's double/single tap for notifs and control center)
• Back button for scenarios where Back/Done is on top left of screen (use of Reachability doesn't really solve it)

I don't miss OnePlus 7 Pro's fingerprint scanner :) Not unless when my iPhone is flat on the table.
