Search and filter

Type text into the filter field and press Return or click Search to search by filename and indexed chemistry metadata. AtomLens uses Spotlight chemistry keys when they are available and falls back to supported chemistry filenames when the richer metadata is missing or still catching up.

• Show only Reactions limits the grid to indexed reaction files.
• Finder-label buttons in the filter bar narrow the result set to matching label combinations.
• Sort controls let you sort by modified date, creation date, molecular weight, or LogP in ascending or descending order.

Result cards

Browser cards show more than thumbnails. A card can include structure preview, formula, path, created and modified dates, molecular weight, LogP, and Finder-label-aware styling.

• The grid remains useful even when filenames are inconsistent because AtomLens surfaces chemistry metadata directly on the card.
• Cards update as metadata and thumbnails arrive.
• If AtomLens has not found supported chemistry files yet, it shows a clear empty-state message instead of an unexplained blank grid.

Selection and preview

The Local Files panel supports mouse and keyboard workflows.

• Single-click for one file, Command -click for multi-select, Shift -click for ranges, and Command-A to select all visible results.
• Double-click a card, press Return , or use Open Selected to open the current selection.
• Press Space for in-app Quick Look without opening the file into a full document window.
• Use Show in Finder when exactly one file is selected, or the Share button for standard macOS share destinations.
• Use Managed Repository > Copy to Managed Repository to import copies of selected local files into AtomLens-managed storage.
• Use Managed Repository > Move to Managed Repository... when you want AtomLens to import selected local files and then move the originals to the Trash. AtomLens asks for explicit confirmation before moving originals.
• The Local Files panel never deletes arbitrary files. Deletion is available only for AtomLens-owned entries in the Managed Repository.

Spotlight and Finder labels

Molecule Browser is deeply tied to macOS system metadata.

• Spotlight makes chemistry identifiers and properties searchable outside AtomLens as well as inside the browser.
• Finder labels are visible on cards, available as filters, and editable from the bottom toolbar.
• Existing non-color Finder tags are preserved when you change labels from AtomLens.
• Quick Look previews work in Finder and in the AtomLens browser flow.
