I am coming from the Blackberry days and was accustomed to that notification light which flashes when there is something outstanding on your phone. Outstanding in this sense can mean an email was not read, a call was not answered or you have a message that you did not get around to reading. This was handy for me and i found that at times it got my attention to the issue at a faster rate. I do not know if it a case where i do not understand how to set this up on my android device but i went searching and i did not see any indication of such a feature being present. I really misses that.
