What's New Since v0.5.0

• 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.

Why This Instead of a Full IDE?

• Faster startup and lower UI overhead for quick edits.
• Focused surface: editor-first workflow without project-system bloat.
• Native Apple-platform behavior across macOS, iOS, and iPadOS.

Download

Prebuilt binaries are available on GitHub Releases.

GitHub Releases (Stable)

Best for direct notarized builds and fastest access to new stable versions.

• Latest release: v0.5.1
• Channel: Stable
• Architecture: Apple Silicon (Intel not tested)

App Store

Best for users who prefer Apple-managed installs and updates.

• Download: Neon Vision Editor on the App Store
• Channel: Store

TestFlight (Beta)

• Channel: Beta

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)

• 0.5.0 milestone: quality + trust release (updater reliability, CSV safety, cross-platform polish, accessibility, release gating). Tracking: Milestone 0.5.0
• Updater diagnostics and support triage surface. Tracking: #24, #35
• CSV/large-file safety and table-mode path. Tracking: #25, #26
• iPad settings density and markdown preview parity polish. Tracking: #12, #13
• Session restore precision and navigation upgrades. Tracking: #34

Known Issues

• Open known issues (live filter): label:known-issue

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.

• Added updater staging hardening with retry/fallback behavior and staged-bundle integrity checks.
• Added explicit accessibility labels/hints for key toolbar actions and updater log/progress controls.
• Added a 0.5.0 quality roadmap milestone with focused issues for updater reliability, accessibility, and release gating.
• Improved CSV handling by enabling fast syntax profile earlier and for long-line CSV files to reduce freeze risk.
