Mail preview pane spacing is overly wide
I upgraded to Monterey and am finding several issues with Mail. One is that the 'top' (preview) area is spaced wider than it was in Mojave or High Sierra. I've attached a side-by-side pair of screenshots, for comparison.
Is there a setting that I'm missing that governs the spacing? Like everyone, I receive a 'ton' of emails daily -- I would really appreciate the old, more-compact view. Is that possible??
