Hi Bernd,
scrollbar maybe nice but does not work for dashboards in my opinion, as they are intended to be displayed on different devices. Especially when the wall mounted display has a different resolution as my own laptop display. When the dashboard is designed on the big screen it looks good on this particular display, but when I open this dashboard on my laptop, I cannot see anything as some elements are squished together, others are too big. So the same dashboard does not work on my laptop.
On the other side, when designing a dashboard on my laptop, the same dashboard on a big wall screen is too small and does not resize properly.
I hope that there is a different way for this.
Best Regards
Markus
