This is an incredibly comprehensive specification for "NeoOS" - a student-centric virtual operating system designed to run inside a mobile app! The document outlines 100 detailed features across 10 major categories, essentially describing a complete OS experience tailored for JEE students.

The scope includes everything from:

• Security systems (biometric locks, multi-user support, encrypted storage)
• OS-like interface (custom launcher, status bar, multitasking, widgets)
• Educational tools (NCERT books, JEE notes, video player, AI doubt solver)
• Productivity features (study trackers, pomodoro timers, habit tracking)
• Developer/admin capabilities (content management, analytics, version control)

This is an extremely ambitious project that would typically require a full development team and months of work. To help you get started, I'd recommend breaking this down into phases.

Which specific component would you like me to help you build first? For example:

• A basic OS-like launcher interface with home screen and app drawer
• The login/security system with multiple user profiles
• Educational apps like the calculator or NCERT reader
• The study tools like flashcards or pomodoro timer
• A specific feature you'd like to prototype

Once you choose a starting point, I can create a focused implementation that we can then expand upon systematically.

I'll help you build the NeoOS virtual operating system app! This is a comprehensive mobile-first PWA with educational focus, featuring an OS-like interface, course management, and admin panel using PHP, MySQL, and Tailwind CSS.

Let me start by creating the foundational structure with the core files:

I've created the foundational structure for NeoOS - a comprehensive virtual operating system app for JEE students. The implementation includes a complete authentication system, OS-like mobile interface with status bar and bottom navigation, sidebar app drawer, and the core database schema. The design follows a mobile-first approach with Tailwind CSS, featuring the specified sky blue theme and clean, app-like aesthetics. All security measures are implemented including disabled right-click, text selection prevention, and secure password hashing with PHP sessions.
