What Dennis said is true for manually floating the control.
In my case, I dropped the control off the tab, which then makes it a part of the pane of the front panel rather than the tab. And I used the position controls to place it elsewhere picking coordinates that appear to place it on the tab control, though the control is actually not a part of the panel of any specific.
If the control would happen to be in the same place on every tab, you don't need any of the programming control I show.
If the control happens to be in the same place but only on certain tabs, then you use only the "Visible" property node that I show.
If the control happens to be in different locations on the different tabs, then you need to use the "position" property node that I show.
