Here's a screen shot just to visualize what was mentioned already. The 'Offline', 'Online', and 'Ladder' toolbars are present with small icons and text has been turned off. This monitor's resolution is set to 1280x1024, and even with the Project Browser and Data View opened, there's a good bit of coding space.
To get even more code on screen (or if you have a lower-resolution monitor), you can also zoom out by clicking 'Zoom Out' in the 'View' menu.
