In OSX 10.10 Mail app a message gets read immediately when as soon as it is selected.
Often this happens by accident; i.e. when organising folders, or it gets auto-selected when you delete/move another mail. Suffice to say this behaviour can disturb a workflow.
From other mail clients I'm used you can give it a small offset (few seconds for example) before it is 'Mark as Read'. Does anyone know if OSX has such a setting?
