LayoutKeeper: multi-monitor layout restore

Remembers window positions, Spaces, and monitor identity for macOS external displays

Problem

Plugging and unplugging an external monitor every day makes macOS shove all windows back to the built-in display, costing minutes of manual dragging; tools like Stay restore positions but not the original Space, so the editor, chat, and browser all end up on one desktop.

Solution

Identify each monitor by EDID, save window positions plus the Space/desktop per monitor set, and restore with one click when a display is connected. Support automatic layout switching per monitor combination plus conflict detection and manual fixes.

Users

macOS developers, designers, and remote workers who switch between external monitors daily

MVP

Read EDID to identify the current monitor set; save and name a layout (positions + desktop numbers); one-click restore after plugging/unplugging; manage multiple layouts in a list; open-source core with paid sync/team profiles

Revenue

One-time purchase ($10–15) or open source with a paid pro tier; enterprise profile distribution

Why now

Hybrid work makes monitor switching routine while macOS still forgets Spaces; an open-source project already proves the approach, so an indie dev can win on polish
