Last year I found this:
It is pretty fricken amazing. Giving what my clients have wanted for years. A back and Forward web browser like navigation to FIleMaker.
I did find it a little buggy so I changed it to navigate by layout No instead of Layout Name.
But I still have issue occasionally when the navigation appears to looses it way, or if the user opens to a new window to compare data between two layouts the second window navigation get out of sync (and for good reason).
Also, if a scripted navigation goes to a layout to prep data before it goes to the displayed layout the back button will take them to a layout they do not want, and I do not want them to see either.
I am curious if anyone on this board has experience with this product that I could ask some questions.
Or if someone has built, or found, another option to do a similar thing.
