forced to scroll emails horizontally to read
With additional vertical message viewing pane, content is clipped because ads take up too much vertical space. Ads should be at the bottom as a horizontal strip so I don't have to scroll so much to see email content. Makes that view useless and more work than when it was either or on msg list vs entire email.
while there's a horizontal layout for msg list and email view, there's so much top and bottom and fonts are so big that you don't see much of either. I think the Ads horizontally might work better since it shouldn't be as large as either of those panes.
