See about removing one set of ColorTableCellEditor and ColorTableCellRender classes
There are two versions of ColorTableCellEditor and ColorTableCellRenderer, one pair in Plotting, the other in Runtimemonitor. They're almost identical; there's basically one main difference, the ones in Plotting make use of an override of Color: org.kepler.sms.Color. There are 42 references to this version of Color in Plotting. Ideally we don't replicate code or override classes, so see about removing this Color class and let both modules use one set of the ColorTableCell* classes, moved into the Gui module.
