- * A simple utility class for generically masking elements while loading data. If the {@link #store}
- * config option is specified, the masking will be automatically synchronized with the store's loading
- * process and the mask element will be cached for reuse.
+ * <p>A modal, floating Component which may be shown above a specified {@link Ext.core.Element Element}, or a specified
+ * {@link Ext.Component Component} while loading data. When shown, the configured owning Element or Component will
+ * be covered with a modality mask, and the LoadMask's {@link #msg} will be displayed centered, accompanied by a spinner image.</p>
+ * <p>If the {@link #store} config option is specified, the masking will be automatically shown and then hidden synchronized with
+ * the Store's loading process.</p>
+ * <p>Because this is a floating Component, its z-index will be managed by the global {@link Ext.WindowManager ZIndexManager}
+ * object, and upon show, it will place itsef at the top of the hierarchy.</p>
