Custom width of Icon Area of the QuickCustomizeTool
The area I am referring to is known as the Icon Area of the QuickCustomizeTool. The width of this area is defined by the size of the checkmark which internally is hardcoded to be 21x20. There is no way to easily change this value.
Could you please add a new feature to the API in order to set the checkmark size (or the background width).

I second Knut. Due to this shortcoming, Infragistics Quick Access Toolbar dropdown does not look good at high DPI scaling. Try 200% DPI for example.
