What if each zone on an ultrawide could behave like its own display?
This is a window management approach designed for ultrawide and multi-monitor Windows setups.
Unlike traditional window managers that only resize and reposition windows, each zone can be presented to applications as its own display area. When an application queries the dimensions of the display it is running on, it receives the bounds of that zone rather than the entire physical panel.
This allows applications to maximize naturally inside a zone, while fullscreen content can also remain contained within that same zone instead of taking over the entire ultrawide display. This behavior is not tied to a specific application, website, or media player; fullscreen video playback can remain inside the selected zone across different types of applications and content sources.
The system also supports multiple layout profiles, per-zone wallpapers, taskbar placement within a selected zone, and independent use of applications across different zones.
A major focus is preserving the native Windows experience. The Windows desktop, taskbar, window system, and application interfaces are not replaced with a custom environment. Normal Windows behavior such as maximizing, fullscreen mode, task switching, snapping, and everyday desktop interaction remains intact.
The goal is for the zone system to integrate into Windows rather than sit on top of it as a separate desktop layer.
Individual zones can also be exposed to screen-sharing, streaming, and capture applications as selectable display areas. This means a single zone can be shared or broadcast directly without manually cropping the physical monitor or relying on window capture.
The rest of the ultrawide can continue to be used normally while only the intended zone is being shared.
Still in development, so feedback, questions, and edge cases worth testing are welcome.
