The RadGallery item has a property SelectionMode, inherited from ItemsControlSelector.
But it is not implemented.
I would like to use the Gallery to select multiple options instead of only one:
*the gallery shall keep open on select one item
*the items shall toggle selection on item click

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.

Pressing Alt to activate the KeyTips and then Alt+Tab leads to NullReferenceException (especially on slower machine )

If you have RadRibbonView control and xaml and design views are open, when click on some ribbon control (e.g. Tab or Button), the design view gets the focus and Smart Tag adorner is open. Moreover, the menu cannot be closed using "Close" button, but only when click outside the ribbon.

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.

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

If  OS Taskbar location on the screen is set to a value different than bottom and the RibbonWindow is in maximized state, the taskbar placement is not respected and part of the RibbonWindow could be hidden.

Reproducible on Windows8 and Windows7 OS.

 A black bar appears around the content of the window when in Maximized states and the project is compiled for .Net4.0.

Extend the focus navigation in the control to match the MS Office navigation

Will be available in Q3 2015 Release

Currently, the RadRibbonGallery control provides the PopupViewportHeight property that sets the Height property of the ScrollViewer, which hosts the RadGalleryItem instances when it is expanded.

We could introduce a property, for example, PopupViewportMaxHeight that will set the MaxHeight property of the ScrollViewer. This way, if the height gets higher than the value specified for this property, a vertical scrollbar should appear.

Unpinned RibbonView content popup is not rendered correctly (has invalid width) when the application main window is of type RadRibbonWindow and in Maximized Mode.

Add support to show the system menu on the RadRibbonWindow element when IsWindowsThemeEnabled=False and the Shift + right mouse button is clicked on the icon on the taskbar.

The MinimizeButton of the RadRibbonView have mismatched states(When the ribbon is collapsed the arrow should be pointing Up, and when the ribbon is collapsed should be pointing Down) not the other way around

Drawing graphics inside the RadRibbonWindow causes performance hit. More information and videos in the support thread

The title bar has a fixed White Background set. The workaround is to set the TitleBackground of RadRibbonView to Black.

The feature should be similar to the TabStripAdditionalContent(https://docs.telerik.com/devtools/wpf/controls/radribbonview/how-to/howto-additional-content-near-help-icon)  of RadRibbonView and RadTabControl. It would be useful to include additional information and functionality like in the MS Office tools. For example the Outlook app (check the attached image).
