All Implemented Interfaces:
ImageObserver, MenuContainer, Serializable, Accessible, BasicCoordPanel.CoordStack
public class VariableCoordStack extends JPanel implements BasicCoordPanel.CoordStack
Coordinate stack implementation that can hold a variable number of coordinates, which can be rearranged in the GUI. Lines may be added as required, and at any time the first N lines may be displayed without discarding the hidden ones.

The implementation of this and its interaction with the MatrixPositionCoordPanel is a bit scrappy. A rewrite including better thought out coordinate GUI pluggability in CoordPanel would not be a bad idea.
