No more red dot on scroll bar in Visual Studio 2012

At Visual Studio 2010, there will be a red dot(s) on scroll bar indicated where your code has errors. Also a other color dots for other message etc.

But after installed Visual Studio 2012, I cannot see this feature anywhere, tried toolbar-options, nowhere to found.

Am I miss something? Or Microsoft just removed this feature.

{EDIT}

Sample of Visual Studio 2010 enter image description here

And Visual Studio 2012, where these nice little dot candy go? enter image description here
