fullscreen toolbar

Hi,
LO: 6.1
OS: Win10

In full screen mode, is it possible to have vertical toolbars such as Format and Standard?

Alternatively, I tried to customize the fullscreen toolbar by adding format & standard functions, but when I switch to fullscreen mode, in LO 6.1 it is displayed as some rectangular shape toolbar, not as in non fullscreen mode; any solution?

My goal is to have as maximal hight view as possible, using 16:9 screen format, so as to put the menu and tools on the side in a vertical way.

Thanks
