This dialog allows you to set a number of properties related to the <label>Project</label>. A Project is a saved set of layers and their settings, as well as other information required to restore the project from disk.<p>
<tr><td><label>Project title</label></td><td>A descriptive title for the project. This title will be displayed in the title bar of the QGIS window</td></tr>
<tr><td><label>Selection color</label></td><td>Selected features are displayed on the map using this color.</td></tr>
<tr><td><label>Background color</label></td><td>The color of the map canvas.</td></tr>
<tr><td><label>Save paths</label></td><td>Ability to save the paths as absolute or relative.</td></tr>
<tr><td><label>Layer units</label></td><td>Choose the units appropriate for the layers in the project.</td></tr>
<tr><td><label>Precision</label></td><td>Use the manual setting to set the precision of the display in the status bar. As the mouse is moved over the map canvas, the coordinates are updated and displayed in the status bar using the precision you choose. Automatic (the default) results in a default precision based on the map units.</td></tr>
<tr><td><label>Digitizing</label></td><td>This allows you to set the snapping tolerance in pixels, the line width used when digitising and the color for digitised lines.</td></tr>
The Coordinate Reference System (CRS) tab allows you to set the projection for the current project and enable on the fly transformation. You do not need to have a saved project to setup and enable 'on the fly' CRS transformation.
<p>
To use 'on the fly' CRS transformation, click the <label>Enable 'on the fly' CRS transformation</label> checkbox. Then choose the projection for the project (map canvas) from the list of Geographic or Projected coordinate systems.
