I managed to hide the ApplicationButton of my RibbonBar by setting its visibility to hidden.
But the space where the button was is still visible, see attached screenshot 1, I would like have the first RibbonTab start at the very left, see screenshot 2.
Is this possible? If not, is it at least possible to set the color of the space where the button was to white?
Thanks a lot!
Screenshot 2: It should look like this:
