Treedent transforms tab chaos into clarity, using intuitive tree-structured navigation designed for focus and flow. Treedent is a privacy-friendly tree-style tab manager for Google Chrome. It transforms overwhelming tab chaos into a structured, collapsible tree. Tabs opened from a page stay linked as children, so browsing sessions keep their context. Whether you work with research-heavy workflows, many windows, or long-running sessions, Treedent helps you stay organized and keep control. Treedent v2 introduces a rebuilt runtime focused on reliability: session state is managed authoritatively in the background, with deterministic persistence and restoration. ▪ Authoritative Session Runtime (v2) Treedent now uses a background-owned source of truth for session and tree state, improving consistency and reducing drift. ▪ Tree-Style Sidebar View tabs and folders in a nested hierarchy and collapse branches to reduce noise. ▪ Drag-and-Drop Reordering and Nesting Move tabs or whole branches exactly where you need them in the tree. ▪ Search, Multi-Select, and Bulk Actions Find items quickly and apply actions across multiple tabs at once. ▪ Snapshot History and Restore Capture workspace snapshots and restore full sessions or individual snapshot windows. ▪ Deterministic Startup Recovery Treedent applies explicit restore rules for restart/crash scenarios and avoids accidental session overwrite. ▪ Tab and Branch Operations Activate, pin/unpin, duplicate, refresh, mute, discard, close, copy link, and run branch-level actions. ▪ Window Workflows Move selected items to new/existing windows and import trees from other windows. ▪ In-Page Sidebar Mode Use Treedent in Chrome side panel mode or in-page injected mode with configurable position, width, and behavior. ▪ Deep Focus and Auto-Collapse Focus on one branch at a time and reduce unrelated tree noise during tab switching. ▪ Options, Logs, and Debugging Configure behavior, language, and styling, and inspect logs/snapshot/runtime diagnostics directly in the extension UI. ▪ Flexible Theming and Styling Use built-in themes, live preview, and advanced style settings including custom theme workflows. ▪ Privacy-First Design No hidden telemetry. Your tab/session data stays local in your browser. • Optional Cloud Sync Sync trees, workspaces, and settings across devices (planned, opt-in). • Collaboration Features Shared workflows and multi-user session capabilities are planned for future releases. • Fixed child tabs created from the sidebar appearing outside mirrored Chrome tab groups. • New child tabs now join the correct browser tab group

persistence replay fallback behavior when journal entries cannot be safely applied. • Fixed assorted sidebar and runtime stability issues across drag-drop, command dispatch, and state refresh flows.
