Do you mean so that you can toggle between the editor and the help page you last visited?
If so then I agree that this would be a nice feature, I regularly used to find that I would locate the necessary help section and try to implement it in my code only to find that I would need to locate the section of help again because I had misunderstood some small detail.
These days I use Juergen's PDF manual and a switcher utility to flip betwwen the B4PPC editor and the relavent section of help.
