# Main Proofreading Window

The main window has two main areas. 
On the left, the two-dimensional view of the data takes up most of the screen.  A panel of **visualization and proofreading tools** is located on the right.  The main window also has two menu bars in the top left corner and a status bar at the top center.  In addition to the main proofreading window, NeuTu has two additional windows dedicated to 3D body visualization and splitting.
