Zen Math Snipper v3.0 — The Complete GATE & STEM Productivity Suite

What's New in v3.0:
• Dedicated Zen GATE PDF Studio (Alt + P): Standalone PDF exam workspace. Open local PDF exam papers or study books with custom region cropping, watermark removal, and OLED theme inversion.
• Drag & Crop Region Snipper: Click & drag a marquee box around any question or diagram to isolate it into a centered Zen Focus Card.
• OLED Invert Mode (I): One-click toggle to invert blinding white PDF exam papers into eye-friendly OLED Dark or Midnight Blue study cards.
• Reversible Watermark Annihilator (W): Automatically eliminates background watermarks and grey text while preserving crisp black math equations.
• Live Math & Notes Preview: One-click toggle in the Scratchpad that formats your rough notes into styled HTML/LaTeX cards. Automatically highlights question headers (Q. 14), option badges ((A), (B)), superscripts, subscripts, and fractions.
• Clean Math Symbol Toolbar: Quick-insert helper buttons (A/B Fraction, √ Root, ≤, ≥, α, β, ∫, θ, π, ±, ∞) right above your rough sheet.
• Save & Open Notes (.txt): Save your GATE rough sheets as .txt files and reload them anytime across sessions in both PDF Studio and HTML Webpage Snipper.
• Full Mobile & Touchscreen Support: Native touch event support (touchstart, touchmove, touchend) for cropping and interacting on Android phones and tablets (Iceraven / Firefox Android).
• Multi-Line LaTeX & Text Copy (L / T): Smart row-grouping extraction that copies clean math equations directly to your clipboard.

Version 2.0 brings massive improvements and full mobile/tablet compatibility!

What's New:
📱 Full Mobile & Tablet Support: The Zen engine has been completely rewritten to perfectly support touch devices (like Iceraven on Android).
👆 New Touch-Safe Selection: Replaced hover mechanics with a new "Two-Tap" logic for mobile, preventing accidental highlights while scrolling.
⚙ Mobile Action Menu: Tapping a block on mobile now reveals a sleek popup menu to instantly Copy or Delete blocks with your thumb.
📝 Revamped Scratch Pad: Upgraded the Scratch Pad to a rich-text workspace that dynamically anchors to the bottom of the screen on mobile to prevent overlapping.
⏪ Undo/Redo History: Added 'Ctrl + Y' for Redo on Desktop, and added a floating Undo/Redo history widget specifically for mobile users.
💻 Smart Desktop Layouts: The UI now automatically calculates screen margins on laptops to ensure the Scratch Pad and Shortcuts menu never overlap the main content.
