The logic for the activation/deactivation of Tools menu items is not clear

[csnyulas]

The way different Tools menu items for creating class, object property and data property hierarchies are activated/deactivated seems to be random.

For example, at start up none of the three hierarchy creation menu item is active. If I select a class, the Create class hierarchy... item becomes active. If I deselect the class (i.e. no class is selected) Create class hierarchy... item stays active (while the two property hierarchy creation item is still inactive)!
If I select an object property, the Create object property hierarchy... menu item becomes active. If I deselect it, it does not become inactive. If I select a data property, the Create data property hierarchy... becomes active AND the Create object property hierarchy... becomes inactive. All the while the Create class hierarchy... stays active, although I don't have any class selected.

Why can't we just have all the three create hierarchy menu items always active? We should be able to create a class or property hierarchy regardless of which view is active or which class/property is selected. In the wizard we should allow the user to specify the root of the class/property hierarchy.

BTW: There is no way to create an annotation property hierarchy. I guess someone creating a complex ontology may want that, too. But maybe this should be a separate issue.

Note: If we would allow the user to specify the root of the class/property hierarchy in the wizard, as it used to be in previous versions, we could combine the three property hierarchy creation (for object, data and annotation properties) in a single wizard, and therefore have only one menu item for it.
