A list of already predefined "empty" controls commonly used is available in the repository and they can be looked up for by filtering the objects having the names prefixed with "SimpleSwat" (make sure you use "*" in the filter)
Double-clicking on a repository object will enable views for that object: Master, Design, Links and Instances depending on the object type.
The Master View holds the information about Object Settings and Object Attributes which can be edited in-line.
The Design View allows the possibility of adjusting the layout and UI behaviour of the object.
Any changes to the object settings, attributes, design, links need to be saved before they will take effect.
