The miniature main window location is a surrogate for the full size window where pattern drawing takes place. When the gallery is entered it contains a miniature image of the most recent drawing. This drawing can be saved by dragging its miniature image into an empty frame within the grid. Drawings can also be dragged from the grid to the miniature main window. In this manner a copy of a previously saved drawing can be retrieved for further update. Finally, drawings can be dragged from the miniature main window directly to other gallery locations.
