Some people don't like this. If you think this bar is not necessary for you, you can remove it from your blog. As there is no obligation from google's terms and condition you are free to remove it. To remove try the following-

Login to your dashboard. Go to Layout>Edit HTML to open the template editor. Look for and find the place shown in the picture.

Then paste the following code in that place-

#navbar-iframe {
display: none !important;
}

Now click Preview to be sure that everything is alright before saving. And if you ever want to show it again just remove the code.
