Google is exploring a new feature for Gmail on Android that allows users to "mark as read" directly from notifications. This feature is currently being rolled out to a select group of users and is not universally available. Traditionally, Gmail notifications offered options to "delete" or "reply" to emails. Users can also mark emails as read using swipe gestures within the app, which can be customized in the Settings menu. Default swipe actions include Archive, Delete, Mark as read/unread, Move to, Snooze, and None.
