File Operations via Preview Windows
Aside from opening circuit diagrams by double clicking on a circuit's miniature representation, a preview window does also provide some File Manager functionality. Analogous to the Edit Mode for objects in a circuit diagram, the miniaturized circuit diagrams can be selected, deleted, copied between overview windows (or moved by holding down the Shift key), copied to the clipboard, or dragged into the a circuit diagram window.
Please remember, that delete operations and move operations take place on the file system. Therefore, if a miniaturized circuit diagram is deleted, its related file will also be deleted in the file system.
