Drag a Dynamic shape from the Toolbox into the Timeline. After the first insertion of the shape, it is white. It is quite large, so most of the time it is necessary to shrink the shape. To do this, use the handle points located at the corners of the object frame.

In the Properties area  you can enter a name for each shape. This is useful if you assign motion paths to the shapes and need a better overview of the shapes in Manual Input.

You can set the Color of the shape here. A transparency value (A) can also be assigned in the Color picker.

In addition, the shape can have a smooth border. In AquaSoft Stages the softness of the border can change over time if you set this via the curve symbol.

Check the Square box to make the rectangle a square. (For the Ellipse shape, you will find the Circle field here).

The Addition combine mode adds lighter areas in the shape that are below the shape.

In the Gradient section  you can assign a gradient or transparency gradient to your shape.
Possible types are gradient linear or circular or no gradient.

Leave in place: The object is not hidden after playing.
