Although it's useful to be able to access my search history, I don't need to see my search history every time I search for something new. I am also afraid a friend, family member, etc. will use my phone and see something I don't want them to see. It's not that I want my search history deleted most of the time, I just don't want it advertised. It also really doesn't save me much time by clicking on a previous search. The search suggestions in the little gray bubbles (sorry, don't know what to call these) already do that well.
