Open it from where you remember it.

Remember the place, not just the name.

Empty space is part of a mosium grid. Items are not automatically packed into the top-left corner: you choose where they belong, and mosium preserves that placement.

Find frequently used items by remembering positions such as “top right,” “bottom left,” or “next to that empty space.”

Apps, documents, folders, websites, and more.

Add apps, files, folders, websites, and Apple Shortcuts to the same grid.

• Click to open
• Select with the arrow keys and press Enter to open
• Drag files and folders in from Finder and supported URLs from a browser
• Website items can show a site icon when one can be retrieved
• Image and video items can show thumbnails

Show as much labeling as you need.

Choose from three item-name modes:

• Always Visible
• Active Only
• Always Hidden

Use an icon-focused layout or keep names visible when that works better for you.

Organize by collection — and by position.

Full lets you create multiple Collections with different spatial layouts for work, creation, reference, or other contexts.

Each Collection keeps its own item positions and grid size, so switching Collections also switches the places you remember.

Bring it up where you need it.

Invocation Profiles can define a target Collection, placement, window mode, and global shortcut.

Placement options include:

• Monitor Center
• Align the window center to the cursor
• Align the top-left Grid position to the cursor
• A saved Placement Preset

Assign a shortcut to each custom profile.

Built for everyday Mac workflows.

For local items, mosium connects to standard macOS actions:

• Press Space for Quick Look
• Reveal in Finder
• Open folders in Finder
• Relink files or folders when a saved reference is no longer available

The goal is to get you to what you need, not to replace Finder.

Export your layout and settings in one backup.

Use File > Export Backup… to export your Collections and settings.

Import Backup… validates the backup and asks before replacing the current state. Local files and folders may need to be relinked when restoring on another Mac.
