Bug 22551 Hierarchy pane missing "New..." menu item in context menu [type hierarchy]
(R2.0) I can almost use Eclipse like a Smalltalk Class Hierarchy browser. This is one of two problems. My custom perspective has a Packages pane, a Hierarchy pane (which includes methods of course) and a code editor pane. I cannot create a new class that is a subclass of the selected class in the Hierarchy pane. Note that I can do this in the "Types" pane from the context menu. The workaround is to use the Packages context menu, but this does NOT pick up the superclass that I have selected in the Hierarchy pane.

try {
				fHierarchyLifeCycle.ensureRefreshedTypeHierarchy(fInputElement, new BusyIndicatorRunnableContext());
			} catch (JavaModelException e) {
				JavaPlugin.log(e);
				clearInput();
				return;
			}
				
			fPagebook.showPage(fTypeMethodsSplitter);
			if (inputElement.getElementType() != IJavaElement.TYPE) {
				setView(VIEW_ID_TYPE);
			}
			
			setMemberFilter(null);
			fIsEnableMemberFilter= false;
			if (!fInputElement.equals(prevInput)) {
				updateHierarchyViewer();
			}
			IType root= getSelectableType(fInputElement);
			internalSelectType(root, true);
			updateMethodViewer(root);
			updateToolbarButtons();
			updateTitle();
			enableMemberFilter(false);
		}
