I mentioned this topic in passing 2-3 years ago. However, it keeps popping up in my thoughts.
I would find a sidebar as an alternative to the header / footer very interesting, as screens are getting wider and wider these days (as are industrial screens).
And if you're not in full screen / kiosk mode, you also have the start bar of the operating system and the header bar of the browser, which need their space.
Meanwhile, you often have space in the width that you don't have in the height.
Hello MarAlz-RW,
Many thanks for this suggestion.
We have already included this point in our roadmap.
