FancyZones is a window manager utility for arranging and snapping windows into efficient layouts to improve the speed of your workflow and restore layouts quickly. FancyZones allows you to define a set of zone locations to be used as targets for Windows on your desktop. When you drag a window into a zone or enter the associated keyboard shortcut, the window is resized and repositioned to fill that zone. You can also trigger zone selection mode by clicking the non-primary mouse button if the "Use non-primary mouse button to toggle zone activation" setting is enabled. If two zones are adjacent, a window can be snapped to the sum of their area (rounded to the minimum rectangle that contains both). When the mouse cursor is near the common edge of two zones, both zones are activated simultaneously, allowing you to drop the window into both zones. You can drag the window until one zone is activated, then press and hold the control key while dragging the window to select multiple zones.

bspwm is a tiling window manager that represents windows as the leaves of a full binary tree. It only responds to X events and the messages it receives on a dedicated socket. bspc is a program that writes messages on bspwm's socket. bspwm doesn't handle any keyboard or pointer inputs: a third-party program (e.g. sxhkd) is needed in order to translate keyboard and pointer events to bspc invocations. Monitors only show the tree of one desktop at a time (their focused desktop). The tree is a partition of a monitor's rectangle into smaller rectangular regions.
