🪧 SignBuilder v1.3 — The Mini Letter & Grid Update!

Welcome to SignBuilder v1.3! This major update introduces mini letters with the new Grid Mode, massive blueprint upgrades, comprehensive tool integration, performance optimizations, and important bug fixes.

✨ New Features & Grid (Mini Letter) Mode

• Sub-Grid Placement (2x2, 3x3, 4x4): Toggle grid mode with Shift + V to place multiple smaller letters inside a single block space (up to 16 mini letters per block!).
• Dual-Sided Placement: Both the front and back faces of a grid block can independently store and display letters.
• Holographic Preview: Real-time visual holograms now guide your crosshair to the exact targeted sub-cell before placing.
• Full Angle Support: Mini letters seamlessly adapt to floor, ceiling, and 45-degree diagonal backplates with pixel-perfect alignment.

📜 Sign Blueprint Enhancements

• Grid Blueprint Mode: Design and stamp mini letters directly from the Blueprint with Single-Block and Multi-Block word flow modes.
• Smart Banner Stamping: Banner mode now starts placing text directly from where your crosshair aims (horizontal & vertical), instead of forcing placement from the edges.
• Backplate Overflow Protection: Prevents text from spilling out into empty air. Letters that exceed backplate boundaries appear red in preview and are safely excluded.
• Text Persistence: Your entered text and configuration settings are now preserved across GUI sessions.

🎨 Tool Integration & Lighting

• Paint Brush & Eyedropper: Paint individual mini letters with custom colors, materials (wood, metals, etc.), or ✨ effects. Use Shift + Right Click to paint the underlying backplate directly.
• Wrench & Light Modes: Apply all 11 lighting modes (Blink, Pulse, Wave, Motion Sensor, etc.) to Grid signs and empty backplates.
• Wave Mode Sequencing: Improved lighting wave animations to run in a smooth sequential chaser across all angles and diagonals.

⛏️ Drops & Survival Balance

• True Block Drops: Letter blocks and backplates now drop the actual block item itself when mined without Silk Touch, rather than 3x White Concrete.

🐛 Bug Fixes & Performance

• Render Fast-Path (Mesh Caching): Major rendering optimization that eliminates per-frame allocations and lag spikes, ensuring buttery-smooth framerates with zero GC stutter.
• UI Polish: Resolved overlapping text labels and repositioned symbol buttons cleanly within the GUI.

🌍 Localization

• Complete localization support updated across 13 languages (English, Turkish, German, Spanish, French, Italian, Japanese, Korean, Polish, Portuguese, Russian, Simplified Chinese, Traditional Chinese).
