Hi Stephane

Thanks for posting in the Community and for sharing your feedback with us! As a growing company we are continuously looking for ways to make our product more useful and effective for our users. As such would you mind adding your suggestion to our feature request form? Submissions to this form are passed on directly to the product development team for their consideration. 

As a workaround may I suggest adding a hotspot to the page? This will allow you to navigate to another page of your document by clicking on a shape during presentation mode. You can find instructions on how to do this here: Actions (Links) and Hotspots. 

Hope this helps!

Alternatively you can put a hotspot on the page and you can link to the next page. This will allow you to click a part of your diagram and it will bring you to the next page. If you take a look a the article I linked it goes through how you can do this.
