Like Firefox, Chrome etc there should be an option to hide title bar.
I think its unimportant and really uses the big screen portion.
We can do use full-screen mode because of this lacking.
When user can close/minimize/maximize a document/app without using that tittle bar in apps like Chrome, Firefox, etc it because necessary to provide such option to hide Tittle Bar just like LibreOffice provide Option to hide "Status Bar".
User Profile Reset: No
The needed Client Side Decoration to remove/restructure title bar is native code development dependent on operating system and Desktop Environment in use.
