 should manage several widgets together as a group. A row of annotation buttons
 is an example of such a layout.
 
+When splitters are used as a way to hide optional features it sometimes has the
+effect of forcing a window to stay larger than should be required. To fix this,
+it is possible to set the \tt{ignoreSizePolicy} attribute to true. While this
+does solve the window size issue, this technique is inconsistent with generally
+expected behavior and its use should generally be discouraged.
