Improved the compact iPhone toolbar with direct access to Source and a clearer More menu. Added bounded preview recovery when web content is interrupted. Improved PDF export reliability, timeout handling, and error reporting.

1.7.0 adds Quick Edit and a smarter workspace sidebar. • Switch to Source, make a small Markdown correction, and save with Command-S on a hardware keyboard. • Nota6 preserves the original text encoding, BOM, and line endings. • Unsaved-change prompts protect edits when switching files or leaving Source. External disk changes require explicit overwrite. • Opening a file inside the workspace now expands and reveals it automatically. Files elsewhere appear as “Outside Current Folder” with an action to browse their containing folder. Built-in Library and sample documents remain read-only.

1.6.4: • Pin files: long-press a file in the workspace sidebar and choose Pin. Pinned files appear in a "Pinned" section at the top of the sidebar, so the documents you reference most are one tap away. • Simplified Chinese localization: the app interface is now fully localized in Simplified Chinese on zh-Hans devices.

1.6.3: • YAML frontmatter card: a leading --- ... --- block (title / author / date / tags) now renders as a clean header card instead of raw text. (The Open-in-Editor and sidebar Pin features added in 1.6.3 are macOS-only.)

1.6.2 is a stability and robustness update: • Code containing a dollar sign (like "echo $5", or a fenced code block) now displays exactly as written, instead of being misread as a math formula. • Large files no longer freeze the app — files over 25 MB are declined with a clear message. • Markdown saved in legacy Chinese encodings (GBK / GB2312) now opens correctly. • Error messages are localized (English + Simplified Chinese).

1.6 ships a built-in Reference Library — Nota6 is now useful the moment you open it, with no external files required. NEW: BUILT-IN LIBRARY • 12 curated documents bundled inside the app (English + Simplified Chinese), available offline • Markdown / GFM syntax references • Mermaid Diagram Gallery — 10 diagram types with source + rendered output • KaTeX Math Reference — symbols, matrices, common formulas • Code Highlighting Gallery — Swift, Python, Go, Rust, SQL, and more • Reading AI-Generated Markdown — strategies for handling agent output • CLAUDE.md & AGENTS.md spec, README patterns, Design Doc patterns • Nota6 Tips, iPad Keyboard Shortcuts, Themes Showcase • Entry points: a "Browse Library" button on the welcome screen, and a "Library" row at the top of the workspace sidebar ALSO IN 1.6 • swift-markdown parser (Apple's official AST-based CommonMark + GFM parser) — dense LLM-generated documents now parse correctly • View Source toggle (⌃⌘S on iPad) between rendered preview and raw markdown • Sidebar polish on iPad: capsule filter field, focus auto-clear when a file is selected • Numerous rendering and stability improvements
