Description-en: improved dynamic tiling window manager
Key features of i3 are good documentation, reasonable defaults (changeable in
a simple configuration file) and good multi-monitor support. The user
interface is designed for power users and emphasizes keyboard usage. i3 uses
XCB for asynchronous communication with X11 and aims to be fast and
light-weight.
.
Please be aware i3 is primarily targeted at advanced users and developers.
