highlight email from outside the domain will a different color

Highlight the folders that get new mail a different color, because some of us have longer named folders that get covered, even small folder names can we not see its name or that there's new mail (the number) since the right hand window (the one that lists the mail in that folder) cuts into the left hand window that shows the folders. Make all the window sizes adjustable, not just the center one, or make the windows slide over, right and left, to get a full screen of each window- folders, email list, opened email. Otherwise on a phone, that's just too much in too little a space to fill with legible don't sized email.
