This sounds about right...
But I need to be able to dynamically add TEdits to the form. Sort of like an Array of them. Though I can just use a stringrid :\ ...

Ok, what stops you?
The TFrame can be used to swap between different "displays"
Then let's say "Frame3" is visible, and you need edits on it
--- Code: ---with TEdit.Create(Frame3)
Parent := Frame3OrSomePanelInFrame3;
Left := 0;
Top := 50;
// or use align, or anchors....
end;
--- End code ---
If you need to remove them , you can keep them in an array:
TEditArray = Array of TEdit;
but be aware, if you destroy (not hide, but really destroy) the frame, then the edits are destroyed too, and the refs in the array are pointing to random mem
or use TFrame.ComponentCount / TFrame.Components to find the edits, by going over all the components displayed on that frame.
"Components goes by Owner, not by parent. So even if the edits are on a panel, they are owned by the Frame.
Use ControlCount / Controls for parent relationship
