Where's the button to change rotating settings?

Support Basics & Interface

In the old blender interface I was able to set the rotate mode to a mode that keeps the view horizontally stable. In the new one I rotate the view and all of the sudden the whole view is skewed or upside down! Why was the option to keep the view level removed?

user preferences (ctrl+alt+u), input tab, change from trackball to turntable and save as default.

Thank you!
