Release Notes

1.2.0

• Added a primary-only display toggle that disables non-primary monitors while preserving the current primary monitor.
• Added scoped restore behavior so "Enable all" only re-enables monitors disabled by ScreenShift, including after app restart.
• Refreshed the compact popup UI with the AditiKraft color palette, improved monitor cards, and a full-width primary action.
• Improved display-change handling so off-screen windows and taskbar state recover after switching to primary-only mode.
