One of the great things about Mail in Lion is the layout. I am a huge fan of the left-to-right format that was made so popular by iOS. This way, I get to read the first couple of lines of those “enhancement” emails without opening them! Score!
Seriously though, aside from the content preview benefit, one can now view Mail threads as “Conversations” (taking a cue from—and one-upping—Google… nice job). What I found, though, was that when I viewed my inbox conversations, I only could see what was actually in my inbox—i.e. responses to me. The fix? Click the “Show Related Messages” button in the Toolbar and you’ll see your own sent mail neatly in order.
Update: Since Mac Treat #159 was featured in last week’s Kibbles & Bytes, I received a few responses which pointed out that if one does not have a Trackpad (either no laptop or no Apple Trackpad), the Trackpad preferences will not be visible. To that I say, you’re right! If you don’t have a Trackpad attached, you’ll find the same option in the Mouse preferences.
