make the inbox/reading pane bigger and add a NORMAL CONTRAST mode
this is ridiculous, the AD BANNER on the right takes up over half the entire screen, leaving only a tiny column for the first few letters of the folders and just a couple inches of visible area for the inbox and reading pane, and NOW you've added a "SPECIAL OFFERS banner across the entire top half of the screen so the actual inbox pane only shows about 4 emails in the inbox at a time and a few lines of text in an open email - this is completely unacceptable, it is less than 10% of the screen area devoted to the actual entire purpose of reading an email - it is completely unusable.
the contrast of light grey text on an off-white background is almost impossible to read - why can't you add a NORMAL CONTRAST and a HIGH CONTRAST option to make the text easily visible?
