Implement AutoHide functionality in the RadRibbonWindow like the Office 2013 has. 

In Office 2013, the user can click and press on a SplitButton or DropDownButton, which opens the drop-down without releasing the mouse.  The user can move/drag the mouse down to a menu item, then release the mouse to execute the menu item.  This is similar to the way menus work.  Please provide this functionality in the RadRibbonSplitButton and RadRibbonDropDownButton.

RibbonView: А System.InvalidOperationException is thrown when  RadDocumentPane is selected and the ribbon is minimized and its popup is open.

Application title disappears when you change the current theme to Expression_Dark or Windows8.

After you re-select a (RadRibbon)DropDownButton  (wrapped in RadRibbonGallery expand content), the button disappears together with any other content of the RadRibbonGallery.

Possible workaround could be handling DropDownClosed event of the DropDownButton and setting e.Handled = True.

As a workaround set a Margin="0,0,1,0" to the RadBibbonView in order to have the functionality working in the area of the RadRibbonView.

This exception reproduces only if the keytips are enabled and the ribbonview is set as a Content of RadPane (or RadTabItem) that is not selected, and also the MinimizeButtonVisibility property is set to Visible.

The error will occur also if the HelpButtonVisibility is set to Visible.

As a workaround you can set the MinimizeButtonVisibility to Collapsed. Then subscribe for the SelectionChanged event of the pane group and in its handler set the visibility to Visible only when the corresponding pane is selected.

The workaround is setting in the ControlTemplate of the RadRibbonSplitButton in Button x:Name="ButtonPart" setter for a custom style  or Style="{TemplateBinding ButtonPartStyle}" and adding a ButtonPartStyle in the setters of the RadRibbonSplitButton to point to the default RadButtonStyle.

When there are enough items in a RibbonBackstageItem for the ScrollBar to appear, it is clipped by the RadRibbonWindow's header.

Workaround:
1. Extract the templates for RadRibbonBackstage and ScrollViewer
2. Refer the new template for the ScrollViewer in the template for the RadRibbonBackstage.
3. Change the margin for the PART_VerticalScrollBar from 0, -1, -1, -1 to 0, 27, -1, -1.
4. Set the new ControlTemplate to the RadRibbonBackstage in the application.
