How to disable Google Chrome download bar?

How to disable Google Chrome download bar from popping up every time I download something? I prefer to ctrl+j to see my downloads status when I actually want it, not to see a log of every thing I save all the time.

You can use this extension that disables the downloads bar but does nothing else: https://chrome.google.com/webstore/detail/disable-download-bar/gjdldigdojpjlmphnogmcmhojfadfmem

In my current Chromium (47.0.2509.0), in chrome://flags, you can set "Download Status in Notification Center" to "Enabled" which will display downloads in a Notification popup instead of the downloads bar.
