You are a software architect tasked with designing an anti-distraction operating system (OS) for increased productivity and focus.  This OS should minimize interruptions and distractions, allowing users to concentrate on their primary tasks.  The OS should be designed for individuals who struggle with digital distractions and require a streamlined, distraction-free environment.  Your design should consider the following aspects:</p>
<p>**Core Features:**</p>
<p>* **App Restriction &#038; Time Blocking:**  Implement a system allowing users to pre-select allowed applications and allocate specific time blocks for their use.  Any attempt to access unauthorized applications outside designated time blocks should be blocked or require explicit user override with a justification.<br />
* **Website/URL Blocking:**  Enable users to block specific websites or categories of websites known to be distracting. This should include a customizable blacklist and whitelist.<br />
* **Notification Management:**  Create a robust notification system that allows for granular control over notifications from different applications and sources.  Users should be able to schedule notification-free periods or completely silence notifications for specific apps.<br />
* **Visual Simplicity:**  The OS should prioritize a minimalist design with a clean interface.  Minimize visual clutter and unnecessary elements that might draw attention away from the primary task.<br />
* **Progress Tracking &#038; Gamification:**  Integrate a progress tracking system to monitor user focus and task completion.  Consider incorporating elements of gamification to incentivize sustained focus and reward periods of uninterrupted work.<br />
* **Context Switching Prevention:**  Implement mechanisms to discourage or prevent context switching between applications. This might involve prompting users to justify switching tasks or imposing a brief delay before allowing a switch.<br />
* **Customizable Focus Modes:**  Allow users to create multiple customizable focus modes with different levels of restriction and notification settings.  For example, a &#8220;Deep Work&#8221; mode with maximum restrictions and a &#8220;Moderate Focus&#8221; mode with less stringent controls.<br />
* **Data Analytics &#038; Reporting:**  Provide users with data on their usage patterns, including time spent on specific applications, number of interruptions, and overall focus levels.  This data should be presented in a clear and informative way.</p>
<p>**Output Format:**</p>
<p>Provide a detailed design document outlining the core features, user interface design, technical specifications, and implementation plan for this anti-distraction OS.  Include wireframes or mockups to illustrate the user interface.  The document should be approximately 500 words in length.
