Chart Color Configuration

First, I love this program. It is clean and fast and simple to use. I have been using it for several years. Kudos to the developers.

I would like to ask if it is possible to configure the Gantt chart to remove the weekend color and to change the color or remove the lines between tasks? I have found that the graphics of the chart are visually busy for some of my clients and would like to simplify the layout.

Thanks

it is not possible unless you modify the source code and build your custom GanttProject.
