It’s not my code, but on the KB side of 4D you can easily overlook this code pearl.
It was released at a time when many developers hadn’t been working with WP yet.
Tech Note: Custom 4D Write Pro Navigation Panel https://kb.4d.com/assetid=78076
Shown is a component for easy navigation in multi-page 4D Write Pro documents.
I downloaded the Technote, which is only available for partners, slightly modified it and integrated it into my software.
Watch the video, I find it very useful. And I hope that the 4D World Tour 2019 bring us more samples like this.
Have fun Armin

P.S.: My favorite technote from the World Tour 2015 was the Zoom Form example, from Thomas Schlumberger, which didn’t show up anywhere outside the 4D World Tour.

(In my current software the icons and button are replaced with SVGs, so that they are no longer blurred in magnification) Video shows an old v12 database and it works fine with v16/v17r4 too
