Grid & Spaces

Mission Control order still matters

macOS owns the real Space list. GridLion reads that list, renders it as a grid, and converts a selected visual cell back to the live Mission Control index before switching.

This is why stable Mission Control settings matter. If macOS automatically rearranges Spaces by recent use, the underlying order can drift away from the layout you expect.

App-owned visual order

Dragging cells in the picker saves a GridLion-only visual order for the display. GridLion then uses that order for the picker, menu-bar grid icon, persistent overlay, direct jumps, and directional navigation.

The saved order is keyed to stable Space identifiers, so the app can keep the same visual layout even when the visible Mission Control order changes.

Placeholders

Placeholders are empty GridLion cells. They are useful when you remove a Space but want the rest of the grid to stay where it was.

• Placeholder cells can be highlighted and selected in the OSD.
• Committing a placeholder does not switch Spaces.
• The plus control can create a new Desktop through Mission Control.
• Trailing placeholders are trimmed so the grid does not grow stale at the end.

Multiple displays

With separate Spaces enabled in macOS, each display can have its own grid settings, hotkeys, overlay placement, and visual order. Per-display shortcuts can target a specific screen even when the cursor is elsewhere.

If macOS is using one shared Space list across displays, GridLion collapses Space state to a shared scope while still using the physical display for OSD placement and screenshot capture.

Previews and fallbacks

Screenshot previews use Screen Recording permission. When previews are unavailable, GridLion still keeps cells useful with app icons, multi-app badges, titles, and Finder fallbacks for empty Spaces.

Window-mode previews can synthesize inactive Space thumbnails from captured windows and the desktop background. Screen mode uses current-screen captures.
