@Mlipka Windows size does not change or You change the size yourself. All controls, menus disappear. Just page content on window.

@Mlipka

Just page content on windows. No menus, no navigation etc.

@leocg s No. I want app full windowed mode, it's different than full screen mode. "Full screen" in window.

@leocg Yes but without borders, without menus. Just content.

I know there is full screen mode in browsers. Can you do full window mode ?
