Hello,
I guess this is not intentional:
With the blue skin Absolute Zero the menu entries in the title bar (file, edit... help) are invisible without hovering over them. The respective entry in the xml file makes foreground equal to background of "MenuBar.Default".
I changed the entry from
<element id="InlineMenuBar.Default" bg="0,100,0,0" fg="1,20,55" />
to
<element id="InlineMenuBar.Default" bg="0,100,0,0" fg="210,210,210" />
