Second overview ruler in Eclipse

Is it possible to add another overview ruler in Eclipse?
Maybe via a plugin?

It would be nice to assign certain annotations to different overview rulers.
For example the diffs in one overview ruler and the occurrences in another.

Thanks

You use the org.eclipse.ui.workbench.texteditor.rulerColumns extension point to define a column in the editor ruler.

For example this is the standard definition for the annotation and line number columns:

<extension
     point="org.eclipse.ui.workbench.texteditor.rulerColumns">
  <column
        class="org.eclipse.ui.internal.texteditor.AnnotationColumn"
        enabled="true"
        global="true"
        id="org.eclipse.ui.editors.columns.annotations"
        includeInMenu="false"
        name="%AnnotationRuler.name">
     <placement
           gravity="0.5">
           <before id="org.eclipse.ui.editors.columns.linenumbers"/>
     </placement>
     <targetClass
           class="org.eclipse.ui.texteditor.AbstractDecoratedTextEditor">
     </targetClass>
  </column>
  <column
        class="org.eclipse.ui.internal.texteditor.LineNumberColumn"
        enabled="false"
        global="true"
        id="org.eclipse.ui.editors.columns.linenumbers"
        includeInMenu="false"
        name="%LineNumberRuler.name">
     <placement
           gravity="0.9">
     </placement>
     <targetClass
           class="org.eclipse.ui.texteditor.AbstractDecoratedTextEditor">
     </targetClass>
  </column>
</extension>

Changing what is shown in existing columns is probably not possible.
