please add a property AutoCloseOverflowPanel (or similar) to RadToolBar that will cause the overflow panel to close automatically if the user moves the mouse outside of the overflow panel.
Rationale for this request: Consider a situation where RadComboBoxes or RadRibbonComboBoxes are used to modify the Font Familiy and the Font Size of text being entered. If the toolbar isn't given too much space, these controls will be placed on the overflow panel. If the user selects a new font and then wants to continue editing (using the new font)), at the moment he has to click somewhere outside the overflow panel. If he clicks inside the RadRichTextBox, he will most likely click in some area where he has already entered some text and the font family will be set to the font family of the text he clicked into.
For an example, please see my support request 1401504.
