The main window for the GUI is shown in Figure \ref{fig:root.window}.
From here, the user has access to all of the GUI's features.
Command files can be called by browsing for them and then clicking "Run", with arguments specified in the "Arguments" below.
In the future, the user will also be able to set up and run optimization routines from this window, although this feature is not currently available.

The main window also has a console, where commands can be run in Tao exactly like in regular Tao.
The console will also display warning messages if a command produces an error.
