Too many times I am in the middle of writing an email and instead of highlighting a word or section I want to correct, I have highlighted the entire text of the email and sent it all to oblivion. Not even to Trash. It means then composing the email all over again. But what if there was at least one copy of the text in the background that would allow me to Restore the last version or Undo the last movement. Windows Word and other apps have two curved arrrows on the ribbon which allow for going back to or forward from previous drafts. Why not with Yahoo mail?
