Workspaces Core

Each workspace has isolated Electron session partitions (persist:workspace_<id>) — cookies, localStorage, and cache are fully separated. Instant switch, export/import as JSON, custom name/icon/color per workspace. Use cases: work vs personal, per-project isolation, different AI agent configs.

Vertical Tabs Core

Tree-style vertical tabs maximize horizontal space. Features: create/close/duplicate/move tabs, pinning, auto-suspend (memory discard after inactivity ~50MB saved per tab), close history (last 50), back/forward/reload, per-tab mute and zoom, favicon tracking.

One-click navigation to: Chat, Kanban, Agents, Browser, Memory, Skills, Settings. Workspace switcher at top. Status footer with server connection indicator. Quick actions: open in browser, restart server, quit. Ctrl+B to toggle.

AI Agents Productivity

Multi-agent system with provider-agnostic model support (OpenAI, Anthropic, DeepSeek, OpenRouter, custom). Role system (Worker, Orchestrator, Supervisor, etc.). Agents can navigate tabs, click, type, scroll, take screenshots, extract content. Real-time dashboard with tasks run, tokens used, success rate. Custom system prompts per agent.

Kanban Boards Productivity

Full kanban system per workspace. Boards with columns (Inbox, Todo, Planned, In Progress, Waiting, Review, Testing, Done, Archived). Cards with title, description, assignee, labels, due date, checklists, comments. WIP limits on columns. Drag-and-drop reorder/move. Color-coded statuses.

Split View Productivity

Side-by-side tab panels. 50/50 layout with resize. Add/remove panels. Workspace-scoped configuration. Perfect for comparison, research, or keeping AI visible while browsing.

Focus Mode Productivity

Pomodoro-based: 25m, 50m, 90m focus sessions + short/long breaks. When active: notifications muted, badges hidden, sounds muted. Timer overlay with remaining time. Integrates with global settings.

Command Palette Core

Ctrl+K — fuzzy search across workspaces, tabs, commands, settings, apps, tasks. Smart scoring: exact matches > prefix > substring > fuzzy. Built-in commands: toggle focus, compact mode, mute all, DevTools.

App Shortcuts Productivity

Pin web apps (Slack, Gmail, Notion, GitHub, etc.) to sidebar. Multiple accounts per app with isolated sessions. Categories by workspace. Mute, suspend/resume per app. Cache clearing per app.

Privacy Core

Built-in adblock with filter lists. Cookie controls: allow all, block third-party, block all. Cache clearing per app or global. Telemetry toggle (off by default). Session isolation prevents cross-site tracking.

Resource Saver Core

Auto-suspend inactive tabs (default: 30 min). Configurable URL exceptions. Memory stats dashboard. Estimated ~50MB saved per suspended tab.

Themes Core

Dark theme (#0A0A12) with purple (#7C6FF0) and blue (#60A5FA) accents. Compact mode minimizes chrome. Workspace-level accent colors. Inter and JetBrains Mono fonts.

System Tray Core

Minimize to tray. Context menu: Show Window, Restart Server, Quit. Background operation with Python backend.

Auto-Update Core

Automatic updates via GitHub Releases (electron-updater). Checks on startup, downloads in background. Configured for Loggableim/lastbrowser.
