Release v1.6.0

New Features

• Ulysses-style Professional Editor: A complete overhaul of the text editing area to replicate the premium aesthetics and functionality of Ulysses.
• High-Performance Rendering Engine: Rebuilt the highlighting system using a specialized regex engine. This ensures 100% accurate rendering for Chinese characters and an exceptionally smooth ("絲滑") input experience with stable font weights.
• Refined Markdown Symbols: Markers like #, *, and ** are now elegantly understated—sized to 70% of base text, 50% opacity, and perfectly bottom-aligned to the text baseline to minimize visual noise.
• Professional Bottom Toolbar: Replaced the old dashboard with a sleek, Ulysses-inspired footer toolbar. It provides instant access to common formatting and a "More Options" popover with a comprehensive set of Markdown shortcuts and structural tools.
• Optimized Chinese Typography: Pre-configured the editor with "PingFang SC", 1.7x line height, and 12pt paragraph spacing for superior readability of Chinese and mixed-language content.
• Drag and Drop support: Documents can now be dragged and dropped into folders, the inbox, or the trash for intuitive organization.
• Trash Functionality: Deleted documents are now moved to a "Trash" folder instead of being immediately removed.
• Markdown Theme System: Added 8 professional themes (Pure, Solarized Light/Dark, GitHub, Dracula, Nord, Monokai, Night Owl) for both editor and export.
• Auto-Title Sync: Document titles now automatically update based on the first line of content.
• Typewriter Mode: Added optional vertical cursor centering for a more focused writing experience.

Fixes and Improvements

• Real-time Settings Sync: Rebuilt the settings backend using a global observer pattern. Changes to Markdown standards or typography now apply instantly across all windows without requiring an app restart.
• Iconography Overhaul: Updated all toolbar icons to a cohesive style, including a new text-based "Aa" font settings button and professional icons for images and themes.
• Enhanced Markdown Support: Improved visual styling for task lists, nested lists, code blocks with backgrounds, and compact link/image markers.
• PDF Export Fix: Resolved issues with blank PDFs and poor dark-mode visibility by ensuring explicit background/text colors and A4 layout.
• Visual Refinement: Achieved a seamless, integrated UI by removing safe area gaps, redundant separators, and consolidating settings dialogs.
• Sandbox Compatibility: Enabled local image rendering and replaced the previous update mechanism with a lightweight, sandbox-friendly checker.
• Localization Audit: Completed and synchronized English and Simplified Chinese localizations across all interface elements.
