When right clicking -> Properties in e.g. a scatter plot on the color selector, you obtain the Properties dialog opened on the color tab which is very convenient. The same functionality should work when clicking on the Color entry in a (cross) tables's legend. At the moment, if you right click->Properties on such an entry, it gives you the legend tab. I guess most people would rather like to jump to the corresponding tab in the properties dialog, not to the legend tab.
