Mosaic for Mac is a professional window management enhancement tool designed to completely transform the way users organize and manage application windows on macOS. Through an intuitive drag-and-drop grid, powerful shortcuts, and highly customizable layouts, it elevates multitasking efficiency to new heights, making it especially suitable for developers, designers, writers, and multi-monitor users who frequently switch between multiple applications and documents.

I. Detailed Overview of the Core Interface and Workspace

Mosaic’s design philosophy is “invisible yet powerful.” It has no main application window in the traditional sense; its core interaction interface is deeply integrated into the system, operating primarily through trigger zones, layout grids, and menu bar icons.

1.1 Trigger Zones

This is Mosaic’s most signature feature. The four edges and four corners of the screen are divided into eight “trigger zones.”

• Location: Move the mouse cursor to the top-left, top-center, top-right, right-center, bottom-right, bottom-center, bottom-left, or left-center of the screen—these eight edge or corner positions.
• Function: After briefly hovering or pressing a configured modifier key (such as Option), a semi-transparent layout grid will immediately appear in the center of the screen.
• Visual Feedback: The grid highlights and displays the preset window layout corresponding to that trigger zone (e.g., the top-left trigger zone typically corresponds to the “left half” layout).

1.2 Layout Grid

The visual grid that appears when a trigger zone is activated is the core of executing window layouts.

• Layout Tiles: The grid consists of multiple rectangular tiles, representing the positions and sizes where windows can be placed.
• Drag and Drop: While the grid is visible, press and hold the title bar of the currently active window, drag it to any tile in the grid, and release the mouse; the window will automatically adjust to the position and size represented by that tile.
• Dynamic Preview: During dragging, the target tile is highlighted, providing instant visual feedback.

1.3 Menu Bar Icon and Control Center

The Mosaic icon in the menu bar is the global control center.

• Quick Layout: Click the icon to directly select a preset or custom layout from the drop-down menu and quickly apply it to the currently active window.
• Layout Management: Access “Edit Layouts…” to enter the core settings panel, where you can create, modify, or delete layouts.
• Preferences: Adjust trigger zone sensitivity, shortcuts, appearance, and all other advanced options.

1.4 Preferences Panel

This is the brain that configures all of Mosaic’s behaviors. The main tabs include:

• Layouts: Manage all preset and custom layouts, with support for creating independent layout sets for different displays.
• Trigger Zones: Enable/disable individual zones, adjust trigger delays and activation methods (mouse hover or modifier key hold).
• Shortcuts: View and customize all global shortcuts.
• Advanced: Control window margins, snapping behavior, excluded apps, and more.

II. Complete Workflow: From Creating Layouts to Efficient Management

Step 1: Create a Custom Layout

1. Click the Mosaic icon in the menu bar, select “Edit Layouts…”, or use the shortcut Command + Option + Control + L to open the layout editor directly.
2. In the layout editor window, click the “+” button in the bottom-left corner to create a new layout.
3. On the grid canvas on the right:
   • Drag divider lines: Divide rows and columns.
   • Click cells to merge/split: Create complex irregular layouts (e.g., a large main window with small side windows).
4. Name the layout on the left (e.g., “Code-Browser-Terminal”), and you can optionally assign it to a specific trigger zone.

Step 2: Apply a layout to a window (three core methods)

1. Method A: Drag to trigger (most intuitive)
   • Move the mouse to a preset trigger area (such as the top-right corner of the screen) until the layout grid appears.
   • Press and hold the title bar of the currently active window, drag it into the highlighted cell in the grid, and release the mouse.
2. Method B: Keyboard shortcut (fastest)
   • Make sure the target window is active.
   • Press a global shortcut, for example Control + Option + → (place the window on the right half of the screen).
   • Or press Control + Option + M to bring up the layout menu, use the arrow keys to select, and press Enter to confirm.
3. Method C: Menu bar selection
   • Click the Mosaic icon in the menu bar.
   • Directly select the layout name you want from the “Layout” submenu, and the layout will be applied immediately to the currently active window.

Step 3: Quickly organize multiple windows

1. Apply a multi-cell layout (such as a three-way split) to the first window.
2. Click the second window you need to organize to make it active, then use the same layout shortcut or menu again; Mosaic will automatically fill the second window into the next available cell of that layout.
3. Repeat this process to quickly and precisely arrange multiple windows into preset complex layouts.

Step 4: Fine-Tuning and Restoring

• Fine-tune window position/size: After applying a layout, you can still drag window edges or use the system’s native split-screen feature to make adjustments as usual.
• Restore original window size: For managed windows, use the shortcut Control + Option + 0 to restore them to their size and position before the layout was applied.
