What's New Since v0.4.32

• iPad toolbar keeps key actions visible more consistently (Settings, Search, Project Sidebar, Markdown Preview).
• iPad Markdown Preview now auto-prioritizes preview space by collapsing the project sidebar when needed.
• Settings polish on iOS/iPad: improved German localization coverage, centered tab headers, and cleaner card grouping.
• macOS top-left window controls are more stable during settings/tab transitions.

Who Is This For?

• Quick note takers who want a fast native editor without IDE overhead.
• Markdown-focused writers who need clean editing and quick preview on Apple devices.
• Developers editing scripts/config files who want syntax highlighting and fast file navigation.

Getting Started (30 Seconds)

1. Install using curl or Homebrew (below), or download the latest .zip/.dmg from Releases.
2. Move Neon Vision Editor.app to /Applications.
3. Launch the app.
4. Open a file with Cmd+O.
5. Use Cmd+P for Quick Open and Cmd+F for Find & Replace.
6. Toggle Vim mode with Cmd+Shift+V if needed.

Install

Quick install (curl)

Install the latest release directly:

curl -fsSL https://raw.githubusercontent.com/h3pdesign/Neon-Vision-Editor/main/scripts/install.sh | sh

Install without admin password prompts (user-local app folder):

curl -fsSL https://raw.githubusercontent.com/h3pdesign/Neon-Vision-Editor/main/scripts/install.sh | sh -s -- --appdir "$HOME/Applications"

Homebrew

brew tap h3pdesign/tap
brew install --cask neon-vision-editor

Tap repository: h3pdesign/homebrew-tap

If Homebrew asks for an admin password, it is usually because casks install into /Applications. Use this to avoid that:

brew install --cask --appdir="$HOME/Applications" neon-vision-editor

Gatekeeper (macOS 26 Tahoe)

If macOS blocks first launch:

1. Open System Settings.
2. Go to Privacy & Security.
3. In Security, find the blocked app message.
4. Click Open Anyway.
5. Confirm the dialog.

Roadmap (Near Term)

• Improve iPad settings layout density and reduce scrolling friction. Tracking: #12
• Expand Markdown preview parity and interaction stability across Apple platforms. Tracking: #13
• Improve toolbar consistency and action discoverability across window sizes. Tracking: #14

Known Issues

Troubleshooting

1. App blocked on first launch: use Gatekeeper steps above in Privacy & Security.
2. Markdown preview not visible: ensure you are on macOS or iPadOS (not available on iPhone).
3. Shortcut not working on iOS: connect a hardware keyboard for shortcut-based flows like Cmd+P.
4. Sidebar/layout feels cramped on iPad: switch orientation or close side panels before preview.
5. Settings feel off after updates: quit/relaunch app and verify current release version in Settings.

Configuration

• Theme and appearance: Settings > Designs
• Editor behavior (font, line height, wrapping, snippets): Settings > Editor
• Startup/session behavior: Settings > Allgemein/General
• Support and purchase options: Settings > Mehr/More (platform-dependent)

FAQ

• Does Neon Vision Editor support Intel Macs?
  Intel is currently not fully validated.
• Can I use it offline?
  Yes for core editing; network is only needed for optional external services (for example selected AI providers).
• Do I need AI enabled to use the editor?
  No. Core editing, navigation, and preview features work without AI.
• Where are tokens stored?
  In Keychain via SecureTokenStore, not in UserDefaults.

Changelog

v0.4.33 (summary)

• Added performance instrumentation for startup first-paint/first-keystroke and file-open latency in debug builds.
• Added iPad hardware-keyboard shortcut bridging for New Tab, Open, Save, Find, Find in Files, and Command Palette.
• Added local runtime reliability monitoring with previous-run crash bucketing and main-thread stall watchdog logging in debug.
• Improved command palette behavior with fuzzy matching, command entries, and recent-selection ranking.
• Improved large-file responsiveness by forcing throttle mode during load/import and reevaluating after idle.

v0.4.32 (summary)

• Added native macOS SettingsLink wiring for the menu bar entry so it opens the Settings scene through the system path.
• Improved macOS command integration by preserving the system app-settings command group and standard Settings routing behavior.
• Improved project-folder last-session restoration reliability by keeping security-scoped folder access active before rebuilding the sidebar tree.
• Fixed non-standard Settings shortcut mapping by restoring the macOS standard Cmd+, behavior.
• Fixed startup behavior when "Open with Blank Document" is enabled so launch always opens exactly one empty document.

v0.4.31 (summary)

• Added an AI Activity Log on macOS with a dedicated diagnostics window and menu entry to inspect startup/provider events.
• Added centralized macOS app command wiring for settings, AI diagnostics, updater, editor actions, and window-level command routing.
• Added a full Flux/command-pattern redesign completed in a parallel session.
• Improved release automation resiliency in scripts/release_all.sh with fail-fast gh auth checks, workflow/runner prechecks, stricter workflow status handling, and retryable asset verification.
• Improved settings startup behavior to preserve user-selected tabs/preferences and avoid redundant refresh work when opening Settings.
