Dear Yahoo

 I must inform you that the new format for Yahoo Mail is awful.
 When you want to reply to a message, with the new format, you can't see what you've written because you can't place the writing cursor where required on the screen. 
 What's more the options for operations for writing e-mails are very very awkwardly situated with this new format, with the old format the options stayed at the foot of the screen, new you have to scroll down the entire history of the whole e-mail conversation, and a bit more, just to click a simple command and then scroll al the way back up again in order to continue working on your message.
  Undoubtedly, judging by these fundamental faults I've stumbled across, this new format must be riddled with faults and bugs.
  I advise you scrap this highly flawed new format as soon as is technically possible and reinstate the old one, which worked perfectly, even though maybe it didn't quite look as snazzy.     
                     Yours faithfully, Mr. D. S. Thomas
