I am going to write a wish, but before that decided to write here.
Sometimes we need to have more than one detail register to refer to the same master register in the same window.
It would be very nice if we had such a possibility:
define an extra detail window as usual, then set parent of that extra window to the "panel" (a Delphi term refering to an area of a window having a Windows handle) of the master window's Tab.
That extra detail window could align to the area of the panel (similar to the normal matrix).
What do you think of that?
