The names related to screen event parameters look a bit weird. When e.g. a handler for snActiveControlChanged is invoked, the *LastControl* parameter reflects the *new* active control. At this time the information about the previously active control is already lost!

If this is really the intended effect, at least this parameter (TScreenControlEvent.LastControl) should be renamed into something more intuitive.

What's the purpose of the Z-ordered form list? IMO all lists reflect the same (activation) order.
