Get someone smarter to re-design the whole appearance
Take a very good look at Gmail, how they put everything there, compact style, for user to see and use. Yahoo Mail is making a big mess every single time in changing the look. You target to make bigger space for putting 'AD', and ridiculously small spacing to read message or manage folder list because it is not expanded and require a click and pop up screen to appear. Rubbish Yahoo Mail
