Somehow I just thought about this on VS Code. Native windows has the top command bar. One of Linux VMs do not... It saves entire line of text... As if I would care about that much vertical space on modern screen.

On other hand. Vivaldi I am trying on phone has this stupid thick bar at bottom on my Android. With essentially bookmarks, back, home, forward and tabs buttons... Significantly more taking visual space...

I am really not sure what is going on in total...
