I have two questions. Please, look at
to understand what I'm talking about.
Question 1: I want to hide the "Customizer Quick Access toolbar" button in the Red rectangle.
Question 2: I don't want any tab, I just want to add buttons in the QuickAccessToolBar but if you look at the image, I want to remove the extra space in the yellow rectangle, it is the space between the RibbonBar and the Grid. Even if I change the height of
the Ribbon to 0, I still have this extra-space.
