Describe the solution you'd like

It would work best if you could add cutom buttons as a collection of elements

In 4.0, you can do this:

    <wpfui:TitleBar>
        <wpfui:TitleBar.Header>
            <wpfui:TextBlock Padding="10">Some text on the left</wpfui:TextBlock>
        </wpfui:TitleBar.Header>

        <wpfui:TitleBar.TrailingContent>
            <wpfui:TextBlock Padding="10">Some text on the right</wpfui:TextBlock>
        </wpfui:TitleBar.TrailingContent>
    </wpfui:TitleBar>

Which will produce a window like so:

The Header and TrailingContent work except for it disables click to select the window and move the window when user clicks on the area with TextBlock, even with IsHitTestVisible of the TextBlock set False.

take a look at #1483 and its PR #1484 If that gets merged, you will be able to add content to the center of title bar too.
