✦ Cross-Browser Bookmark Sharing — View Your Edge Bookmarks Right Inside Chrome

Use Chrome at work and Edge at home? Two separate bookmark sets with no easy way to cross-reference. Now each browser joins its own sync space, and you can follow another space to view its bookmarks read-only in the side panel. No merging, no overwriting — switch between two independent sets anytime.

• Follow other sync spaces to view read-only bookmark copies in the side panel.
• Click any link to open it directly in the current browser — no app switching needed.
• Fully isolated — your local bookmarks stay independent.

✦ Bookmark Cloud Sync — Zero Data Loss, Multi-Device Auto Merge

Say goodbye to data loss from "last write wins." Every bookmark operation is precisely recorded as an operation log; multi-device conflicts are resolved deterministically by the algorithm; deleted items are preserved as tombstones. Preview merge results before joining a space, auto-snapshot before each sync, and a Failsafe anomaly detector blocks unexpected large-scale changes.

• Create or join a sync space for automatic multi-device bookmark sync.
• Preview local-vs-cloud merge before joining, with 3 merge strategies.
• Safety guard: auto-aborts and prompts confirmation when large-scale deletions/additions are detected.
• Browse another sync space's bookmarks read-only in the side panel (no local impact).
• Real-time sync progress and status display.

✦ Bookmark Snapshots — A Time Machine for Your Bookmarks, Every Step Reversible

Auto-snapshot on every significant change, plus manual creation anytime. Browse any version on the timeline, highlight diffs between two snapshots (added/deleted/moved), and restore with one click — the current state is auto-backed up before restore, so every step is reversible.

• Manually create snapshots, browse the full bookmark tree, compare with current bookmarks and highlight differences.
• Auto-snapshot: triggered before cloud sync and on bookmark changes, with smart deduplication to save space.
• Scheduled snapshots (every 6/12 hours, daily, or weekly).
• Import/Export: HTML (Netscape) and JSON formats supported.
• Granular settings: auto-snapshot toggle, max retention count, minimum change threshold, schedule interval.

✦ Lock Tab — Real Protection, Not Just "Pin" — Prevents Close and Navigation

Chrome's pin tab only repositions and shrinks — it can still be closed. VertiTab's Lock provides two layers of protection: close interception, in-page links forced to new tabs, and address bar navigation auto-rollback. Lock persists through browser restarts.

• Closing requires confirmation after lock (Ctrl+W, middle-click, × button all intercepted).
• In-page link clicks open in a new tab — original page stays.
• URL navigation auto-restores; new links open in new tabs.
• Lock state survives browser restart.
• Per-site settings also offer a lightweight "prevent accidental close" option.

✦ Debug Mode — One-Click Site Data Reset for Development and Everyday Use

For developers: one-click clear of IndexedDB, Service Workers, Cache Storage, etc. with hard reload — precisely preserve login cookies. For everyday users: many sites store trial counts, popup flags, and read limits in your browser — clearing resets those restrictions, making the site treat you as a new user.

• Mark tabs or entire sites as "in development"; click the icon to trigger clear + hard reload.
• Toggle individual storage types (localStorage, IndexedDB, Cache, Service Workers, Cookies).
• Cookie exclusion list to precisely preserve auth tokens.
• Per-site config — different sites can have different clear strategies.

✦ Group Management & Productivity

• Close tabs in current group — Right-click submenu to close other/above/below/same-hostname/same-domain tabs, scoped to the current group only.
• Merge groups — Combine multiple groups into one with a custom target name and color; hover buttons to quickly copy group info.
• Auto-collapse inactive groups — Automatically collapse groups after a configurable idle time, globally or per-group, with option to promote as default.
• Save tab URL — Remember a tab's URL, edit it later, and return with one click even if the page has navigated away.

✦ Visual & Accessibility

• Color-blind / color-weak mode — Okabe-Ito accessibility palette for tab group colors, plus a dedicated color-blind theme.
• Custom tab group colors — Override default group colors with any hex value, separate config for light/dark mode, with live preview.

v3.6 is an update that brings bookmarks to life. Whether it's cross-device sync, cross-browser browsing, time-travel restore, or page lock, we want you to rely on your browser with more confidence and keep your focus on what truly matters.
