 On all those buttons, a selectionlistener is added. Thanks to Java8 this can be done in a very clean fashion. And all those handler should do, is to call a method in the controller! The controller takes care of the rest.

+Following this paradigm, the model will never appear in the UI composites, and the UI only delegates everything that needs some thinking right to the controller. I encourage you to make use of Java8 to register your Listener.
+This does not only save code, but also keeps the code clean. Another use-case where you can see its advantage is when you create a table and add its columns. The code is usually extremely long. But thanks to java8 (and its possibility ot pass methods as parameters) you can create table columsn like this:
+
+```java
+	private void createColumns(TableViewer viewer) {
+
+		createTableViewerColumn("Name", 100, 0, part::determineName);
+		createTableViewerColumn("Freq.", 30, 1, part::determineFrequency);
+		createTableViewerColumn("ID", 30, 2, part::determineID);
+		createTableViewerColumn("Synonyme", 90, 3, part::getCoveredText);
+		createTableViewerColumn("Type", 60, 4, part::determineNEType);
+		createTableViewerColumn("Uncertain?", 30, 5, part::determineUncertainFeature);
+		createTableViewerColumn("Numerus", 30, 6, part::determineNumber);
+		createTableViewerColumn("Gender", 30, 7, part::determineGender);
+		createTableViewerColumn("Pseudo", 30, 8, part::determinePseudoFeature);
+	}
+
+	private TableViewerColumn createTableViewerColumn(String viewer2, int bound, final int colNumber,
+			Function<AnnotationFS, String> function) {
+		final TableViewerColumn viewerColumn = new TableViewerColumn(viewer, SWT.NONE);
+		final TableColumn column = viewerColumn.getColumn();
+		column.setText(viewer2);
+		column.setWidth(bound);
+		column.setResizable(true);
+		column.setMoveable(true);
+		// the sorter
+		column.addSelectionListener(getSelectionAdapter(column, colNumber));
+
+		// also add the labelprovider
+		viewerColumn.setLabelProvider(new ColumnLabelProvider() {
+			@Override
+			public String getText(Object element) {
+				AnnotationFS p = (AnnotationFS) element;
+				return function.apply(p);

+
+		return viewerColumn;
