+ * layout</b> to resize both immediate siblings.</p>
+ * <p>By default it will set the size of both siblings. <b>One</b> of the siblings may be configured with
+ * <code>{@link Ext.Component#maintainFlex maintainFlex}: true</code> which will cause it not to receive a new size explicitly, but to be resized
+ * by the layout.</p>
+ * <p>A Splitter may be configured to show a centered mini-collapse tool orientated to collapse the {@link #collapseTarget}.
+ * The Splitter will then call that sibling Panel's {@link Ext.panel.Panel#collapse collapse} or {@link Ext.panel.Panel#expand expand} method
+ * to perform the appropriate operation (depending on the sibling collapse state). To create the mini-collapse tool but take care
+ * of collapsing yourself, configure the splitter with <code>{@link #performCollapse} false</code>.</p>
