x11-wm/subtle 0.11.3224_1 FreeBSD

subtle is a manual tiling window manager with a rather uncommon approach of tiling: instead of relying on predefined layouts, subtle divides the screen into a grid with customizeable slots (called gravities). For better understanding, the default config uses a 3x3 grid and maps each gravity to one key of the numpad. With those keys, windows can be moved directly to the desired gravity -- the same can be done with tagging rules in the config.

Another unique concept is the strict tagging: unlike other tiling window managers, subtle does not allow weak tagging and always maps windows to virtual desktops (called views) with matching tags, regardless of the current active view.
