I use KWin, and it has configurable keyboard shortcuts for basically everything, so I have ones configured to effectively tile windows into halves or corners of the screen.  This makes very good use of 16:9 monitors.<p>But sometimes an overlapping window is very useful.  For example, I&#x27;m watching a fullscreen video, but I want to chat with a friend in an instant messaging app.  I can put the conversation window on top of the video in a corner of the screen where it doesn&#x27;t block anything important.<p>Or I&#x27;m doing some kind of graphical work, image editing, web design, etc, and I only need to see part of a window, but it needs to fill the height of the screen.  I can put other programs on top of the parts I don&#x27;t need to see.<p>Tiling is great, but overlapping windows have their place too.
