The Appearance attribute is applied to a property of the plug-in class. It allows the plug-in creator to specify the height and width style values of the UI element representing the property on the configuration screen.
Example:
public class DisclaimerSelectorPlugin
{
[Appearance(Width = "30%", Height = "30%")]
...
public string DisclaimerText
{
get;
set;
}
...
}
