I was searching in google if I was able to customize the "thread panel" in "vertical layout" mode, to look like the one in apple mail. Where each mail has 4 lines - Line 1: Sender in bold, Line 2: Subject in black, no bold, and Lines 3&4: a little preview of the e-mail in light gray. I think apple did a great job in terms of use of space and optimal amount of information. Can I do that with some tweaking? I uploaded an image to sample it.
