pretty sweet (nice job).
i use openSuSE and KDE so i can hide (disable) title bars and borders for my windows or a window or app. i wrote addon for hiding navbar and bookmarks bar, now i don't have to right one for tabs.
my 'web page is now windowed at 1024 wide and literally top to bottom without 'full screen'...
one recommendation. enable or activate area could be larger or definable as i run my 'taskbar' at top of desktop and use autohide on it. i have to go so high to enable tabs bar, i am activating my taskbar and it covers the tab bar... just saying. again, good job.
