One tiny tool, the whole multi-monitor workflow
Zone layouts, fullscreen confinement, drag-to-snap, single-zone sharing, and global hotkeys — no driver, no runtime, no install.
Zone layouts and a custom grid editor
Start with 25/50/25, 50/50, or thirds, then build your own. The FancyZones-style editor lets you click a shared border to merge two zones or an internal line to split one apart — save as many named layouts as you like and switch between them from the dropdown or a hotkey.
Fullscreen and maximized apps stay in their zone
Maximize an app, run a PowerPoint slideshow, play a borderless-fullscreen video, or hit F11 in Firefox — each snaps into the zone it belongs to instead of taking over the whole display. Placement is event-driven and flush, correcting for invisible resize borders so visible edges land exactly on the zone.
Honest caveat: Chrome and Edge re-assert full-monitor bounds on F11/HTML5 fullscreen and block the in-process workaround, so maximize those browsers instead. Exclusive-fullscreen DirectX games bypass the desktop compositor entirely and can’t be confined.
Drag-to-snap, FancyZones-style
Hold Shift while dragging any window; the target zone highlights and the window snaps in on release. Snapped windows respect the taskbar — they fill the work area, not the space behind it — unless you opt into Cover taskbar.
Share a single zone into any meeting
Toggle a live mirror of one zone from the tray or with Ctrl+Alt+1/2/3. It appears as its own window in Zoom, Teams, and OBS’s native share picker, so you share exactly that region — with whatever’s underneath it — not your whole screen. A dashed frame marks the shared zone for you; viewers never see it.
Global, rebindable hotkeys
Start/stop confinement, hide/show zones, cycle layouts, and shove the focused window between zones — all from the keyboard. Every binding is rebindable from the Shortcuts dialog, with conflict checking against Windows-reserved combos and other running apps.
Tiny, native, set-and-forget
A single ~180 KB exe with zero crate dependencies — no .NET runtime, no driver, no admin, no install, and negligible RAM. The modern main window is drawn with Direct2D (dark gradient, card-grouped sections, pill toggles). Start with Windows and tuck it into the tray so it just runs.
