The visualization of the elements has been realized by the element list, the folder or tree structure of the queued elements. The element list is broadly comparable to the Windows Explorer. All folder elements are displayed in that list. These elements can be deleted, flagged and categorized.
Like in all other sections, there are more options to select, as soon as you click the right mouse button. At the top of the element list, there are also further settings available, e.g. this thumbnail view may be replaced by a list view.
