Bookmark Cloud Sync — Multi-device bookmark management and cloud synchronization based on sync spaces, powered by Merkle-CRDT architecture for deterministic conflict resolution and zero data loss.
Auto-snapshot before cloud sync and on bookmark changes, with smart content-based deduplication to save storage.
Scheduled snapshots at fixed intervals (every 6h, 12h, daily, or weekly).
Import and export bookmark snapshots in HTML (Netscape) or JSON format.
Fine-grained snapshot settings: auto-snapshot toggle, maximum retention count, minimum change threshold, and scheduled interval.
Lock Tab — Pin a tab to its current URL: close attempts now ask for confirmation, links always open in a new tab, and navigation away is automatically reverted. A lightweight "Prevent accidental close" option is also available in per-site settings.
Close tabs in the current group — New right-click submenu for grouped tabs: close other/above/below tabs, or close tabs sharing the same hostname or root domain — all scoped to the current group only.
Color-blind / color-weak mode — Applies an accessibility-friendly Okabe-Ito palette to tab group colors, plus a dedicated color-blind theme.
Custom tab group colors — Override any Chrome tab group color with your own hex value, configured separately for light and dark mode, with live preview.
Merge groups — Combine several tab groups into one from the group right-click menu: pick a target name and color, select the groups to merge, and quickly copy name/color from any group via hover buttons.
Auto-collapse inactive groups — Automatically collapse a tab group after a configurable idle time. Configure globally in settings, or per-group via the right-click menu with an option to promote that value as the new global default.
Debug mode — Mark tabs or whole sites as "in development". A debug icon appears on these tabs; clicking it clears the configured site data and then performs a hard reload. You can exclude specific cookies (including cross-domain auth/SSO cookies) from being wiped.
