We have a RadRibbonView with enabled KeyTips and a RadComboBox control below it.
We focus the RadComboBox and press "Alt + DownArrow". As a result the the RadComboBox is opened and immediately closed and KeyTip is activated and shown and the coressponding RadRibbonTab gets the focus. The expected result is that the RadComboBox is opened, remains opened and no KeyTips are activated.

Expose an event where the key combinations that (don't)show the KeyTips can be customized.

If you delay adding a RibbonView in a RibbonWindow, the RibbonView is placed on top of the window, hiding its TitleBar.

When both Command and IsEnabled of RadRibbonBackstage are bound, the Command has Higher priority. This is inconsistency with the behavior of Buttons and RadButtons. The RadRibbonBackStageItems should work like RadButtons.

The KeyTips of RadMenuItems go behind the menu when hovering over the RadMenuItem. This issue seems to be related to the ScreenTip/ToolTip settings applied on the RadMenuItems - if no such settings are applied, the issue cannot be reproduced.
The Tooltip popup is placed over the KeyTips popup.

When RoutedCommand is used in RadRibbonBackasteItem the OriginalSource is wrong.

RadGallery is used in RadRibbonView  and ListBox under the RibbonView with  DeferredScrollingEnabled set to true. When scrolling the Gallery, the ListBox Scrolls unexpectedly.

Expose properties to control the HorizontalAlignment and VerticalAlignment of the footer content

When Windows Classic theme is applied in Windows7 ( or when XP is used) and the WindowStyle of the RadRibbonWindow is set to SingleBorderWindow, the scrollviewer in the backstage does not work properly

Posibility to use the QAT buttons when the BackStage is open

I assume that even though this is listed under RadControls for Silverlight it will also apply to RadControls for WPF.

Expose property controlling the RibbonGroups Header Background

RibbonBar should set default GroupNames of the RadRadIoButtons used

In SL this scenario is only in OOB mode, with BorderlessRoundCorners.

Allow ApplicationMenu to be editable in Blend. Make sure when clickon the application button the app menu is displayed in blend. Also add panels for the content and footer content for easier content adding.

Add a property to show/hide RibbonWindow Close/Minimize/Restore buttons panel

Add support for direct content of ribbon buttons (like using XAML vector graphics instead of images).

Implement DirectionalNavigation

In application Menu, when hovering the dropdownbutton to open the RightPane, clicking an item in the Pane does not closes the application menu
