Hi, It would be great if there was the option in KDE/ KWin system settings to toggle this (mostly hidden) feature (see http://blog.hanschen.org/2010/04/01/hide-window-border-for-maximized-windows/ for exactly what I mean). It's a great feature, would be cool to make it easier for users to enable it. Even better would be the option to enable it in settings and also toggle it with a keyboard shortcut! Cheers.
