From customer feedback: There should be client methods for completely hiding (in contrast to collapsing) ribbon groups.
Based on customer feedback: When the application menu of the Ribbon bar is opened and should cover external applets / plugins, such as JavaApplets, PDF, Flash etc, it's not rendered on top, but beneath. --- The solution is to add an IFRAME element, a lot like in the menu, combo etc, for IE browsers.
Currently, the ribbon groups are resized automatically, from right to left. The MS Ribbon Framework specifies a property to set the order of the group reduction -- GroupSizeReductionOrder.

Unlike the rest of the Ribbon Items, the Templates have only one level of resizing, where as they need few steps more, to be consistent. Add proper (fluid) resizing to templates by implementing template size.
For the time being you can use the ApplicationMenu withing the RadRibbonBar control.
