New Post: How to specify AutoHide side of AvalonDock?

Hi, I’m testing AvalonDock control included in Extended WPF Toolkit 2.0. I have the following xaml.

<Window x:Class="AvalonDockTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:avalonDock="http://schemas.xceed.com/wpf/xaml/avalondock"
        Title="MainWindow" Height="600" Width="700">
    <Grid>
        <avalonDock:DockingManager>
            <avalonDock:LayoutRoot>
                <avalonDock:LayoutPanel>
                    <avalonDock:LayoutAnchorablePaneGroup>
                        <avalonDock:LayoutAnchorablePane>
                            <avalonDock:LayoutAnchorable Title="Main Anchorable"
                                                         CanClose="False" CanHide="False" CanAutoHide="False">
                                <TextBlock />
                            </avalonDock:LayoutAnchorable>
                        </avalonDock:LayoutAnchorablePane>
                    </avalonDock:LayoutAnchorablePaneGroup>
                </avalonDock:LayoutPanel>
                <avalonDock:LayoutRoot.LeftSide>
                    <avalonDock:LayoutAnchorSide>
                        <avalonDock:LayoutAnchorGroup>
                            <avalonDock:LayoutAnchorable Title="Left Side Anchorable" 
                                                         CanClose="False"  CanHide="False" CanAutoHide="True"
                                                         AutoHideMinWidth="300">
                                <TextBox/>
                            </avalonDock:LayoutAnchorable>
                        </avalonDock:LayoutAnchorGroup>
                    </avalonDock:LayoutAnchorSide>
                </avalonDock:LayoutRoot.LeftSide>
            </avalonDock:LayoutRoot>
        </avalonDock:DockingManager>
    </Grid>
</Window>

When I run the code above, the "Left Side Anchorable" is hidden at left side of window. Then if I click “Auto Hide” button (pin icon) of "Left Side Anchorable", the anchorable is docked to left side of the window. However, if I click “Auto Hide” button again to hide the "Left Side Anchorable", it gets hidden to right side of application instead of left side. Is there way to specify which side I want to hide the anchorable?
