What's Intentionally Missing

We deliberately exclude:

Feature	Why It's Missing
AI Assistant	Unnecessary complexity, often cloud-dependent
News Feed	Distraction, usually ad-driven
Sync Service	Requires accounts, cloud storage
Rewards/Crypto	Not a browser's job
Built-in VPN	Usually upsells, trust issues
Reading List	Use bookmarks
Collections	Use bookmark folders

• Keyboard shortcuts (22 remappable shortcuts)
• Proxy configuration
• Data retention periods and auto-delete schedules
• Cookie policy
• User agent string
• Download location
• Start page

Settings We Don't Include

• Telemetry opt-out (there's nothing to opt out of)
• Data sharing preferences (we don't share data)
• Personalization options (nothing is personalized)
