Sorting
It is preferred to name search criteria in a way that it expresses also the ordering direction. Thus, it is better to have "New" and "Old" than having a "by date" criteria and a separate selection for the ordering direction ("Ascendent", "Descendent").

List creation
Some examples include:
 * The Universal Language Selector supports to select multiple languages for some contexts. Languages are added to a list following an horizontal layout. Users can remove elements from the list by clicking on the close button of each one.
 * The Upload Wizard shows a list of files where they can be added by dragging, and can be removed by acting on each element.
