Currently, when you perform a search the returned list of messages does not enable or show the snooze button for individual messages, or in the top toolbar.
Enable snoozing emails from search results.
Pretty easy to reproduce. Just run a search that returns multiple messages, and you’ll notice there’s no snooze button on the message on hover, or in the toolbar. This would be HUGELY beneficial for cleaning out large backlogs of messages by simply shoving them forward via snooze and allowing me to focus on purging the cruft.
