the Quick Access Toolbar (the toolbar in the window title bar) is available both in the Ribbon User Interface (below left) and in the Classic User Interface (below right) of PDF-XChange Editor.

However, it seems that there are two independent versions of the Quick Access Toolbar, one in the Ribbon User Interface and another one in the Classic User Interface.
I would like to use the same (heavily customized) Quick Access Toolbar in the Classic User Interface and in the Ribbon User Interface:

Is this possible? If it should not be possible, I'd like to suggest that the same Quick Access Toolbar is used in both User Interfaces, as a feature request.
The same applies to the "Other Tools" button. I have also customized this button significantly, and would like to use the same customized "Other Tools" button both in the Classic User Interface and in the Ribbon User Interface:

Thank you
David
