Currently, a ScreenTip is opened 500 milliseconds after you hover the associated item. This is a hardcoded value that cannot be changed. Add a property to change this. For example another attached property in the ScreenTip class.

For example: ScreenTip.InitialShowDelay="1000"

The backstage of the RadRibbonView cannot be opened when the control is placed inside a WinForms application. 

Expose a property to control the visibility of the backstage back button.

Please support the new Office Simplified Ribbon: https://support.office.com/en-us/article/use-the-simplified-ribbon-44bef9c3-295d-4092-b7f0-f471fa629a98?ui=en-US&rs=en-US&ad=US.

The attached project demonstrates a possible approach for handling this - by editing RadRibbonWindow's control template and specifying a converter for the PART_Icon Image's Width and Height bindings. The converter in turn takes into account the DPI of the current monitor.

Currently, the minimized content of the ribbon opens up in a Popup element which leads to issues when positioned between two (or more) monitors. Introduce a feature that allows the content to opens in an Adorner element. 

Items in RadCollapsible are not rendered correctly on Windows7 with DPI 150% and UseLayoutRounding set to true and ItemSpacing is set to more than 0.
