I3 (window manager)

i3's primary design goals are to possess well-written, documented code that encourages user contribution; to use XCB instead of Xlib; to implement multi-monitor features correctly, so that each workspace is assigned to a virtual screen, and monitor additions and removals are non-destructive of windows; to implement different modes, in a manner similar to that of the text editors vi and vim; to use a tree as the abstraction (and underlying data structure) for window management; and to implement UTF-8 character encoding. ==Features==

i3's configuration is done via a plain text file (usually found in ~/.config/i3/config), which can be customized without any sophisticated programming knowledge. i3 also supports the use of multiple monitors. Floating pop-up windows Even though i3 is a tiling window manager, specific windows, such as password pop-ups, are not displayed as new tiles by default; they are always stacked in front of tiled windows, unless in full screen mode. These floating windows can be moved and resized freely, just as they can in stacking window managers and popular desktop environments like GNOME or KDE Plasma. The authors of i3 intend floating windows to be used for pop-up windows only. ==Gallery==
