Getting Rid of Title bars ALWAYS a Good Idea and save some space on your screen especially for users with small screen resolution and increase the visibility of contents on currently opened windows in full-screen mode.

It’s really convenient especially for applications comes with a separate Title Bars and decoration buttons instead of merging them with the application WIndow as we have seen with some applications like Nautilus File manager. The Modern Header Bar of Nautilus File manager under GTK3 (Window management) includes the decorations buttons, search buttons, icons viewing options, ….. etc. which gives Nautilus file manager a compact looking regardless it’s in full-screen mode or not.
Both Gnome Shell Extension does the same job. (No Title Bar) comes with a Graphical user interface to apply some modifications for the Window control button position, choosing whether to view the Application Menu Name or the Window Name.
