Project Quality is a field that represents the quality of the work on the project
The quality field is currently not calculated in any way, but is included so you can manually set a quality level on a project.
This setting allows you to edit or create new Qualities that can be set on a project.
The image below shows the default qualities: Low, Medium and High:
You can add new qualities or edit the ones in the table. Clicking on the palette icon shows a color picker dialog.
The red "X" deletes the row.
