Optionally auto-save the current tabs when you switch. Give each space its own color and icon. [Categories] Organize spaces up to three levels deep, reorder by dragging and tell them apart by color. Open favorites and recent spaces instantly. [Tab groups] Chrome tab groups are saved and restored with their names and colors. [Pinned tabs] Pin the tabs you always need, like email or chat. They stay open when you switch spaces and are never saved into a space. [Bulk actions] Select tabs to open, move to another space, group, archive or delete in one go. Select all and Shift-click ranges. [Undo] Take back a delete or archive right after it happens with Ctrl/⌘+Z. [Right-click save] Save the page or link you are looking at into any space from the context menu. No trip back to the dashboard. [Share spaces] Export only the spaces you choose as a file or a share code; the recipient adds them to their own data. Great for project handovers and sharing with your team. You can strip everything after "?" in URLs before sharing. [Copy URL lists] Markdown, title + URL, or URLs only, straight to the clipboard for reports and notes. [Search & shortcuts] Filter tabs by title or URL. Ctrl/⌘+K to search spaces, / to filter tabs, Ctrl/⌘+S to save. Press your mouse's Forward button to jump back to the dashboard. [Backup] Timestamped backups to a dedicated Google Drive folder. Choose how many to keep and restore any of them from a list (your current data is set aside first, and you can undo). JSON export/import and scheduled automatic backups (hourly, every 6 hours or daily) are included too. [Auto-tidy unused spaces] Spaces unused for 30–365 days are archived or deleted automatically (deleted spaces stay in a 30-day trash). Favorites and the space you are on are never touched. [Look & language] List and card views, dark mode, and 10 languages: English, Japanese, Simplified and Traditional Chinese, Korean, Spanish, Portuguese, German, French and Italian. Switch anytime in Settings. ■ Your data Everything you save stays in your own Chrome (chrome.storage.local). Nothing you browse is sent anywhere.
