Keep it simple!! If it isn't broke, don't fix it. Most people use their email and want it to be stable without any changes, so they can use it without having to look around for a box to click. Keeping it the same allows us to use our email properties efficiently (even in the dark) because everything is always in the same place! Otherwise we could switch email accounts from Yahoo to Google or another source since there wouldn't be any reason to stay with Yahoo. If we have to relearn the changes anyway why stay loyal to Yahoo?
