Sorry, I still cannot find a Layout list in the MainBar :-(

My IDE model contains:

procedure TIDEForm.MakeVisible(inFront: boolean = True);
begin
   ShowControl(nil, inFront);
end;

How are these affected by an added default parameter?

The user specifies the position when undocking a form, whereupon the 
form is resized to its UndockedWidth/Height. That's Delphi docking 
convention - see also DockRect.

Thanks :-)

No, but it should work when Screen.Monitors returns the true monitor 
bounds. More complicated is exclusion of the TaskBar...

Let me know when you can spend some time for IDE docking.

Thanks for the links :-)
