h3pdesign/Neon-Vision-Editor v2.1.0 on GitHub

[v2.1.0] - 2026-10-23

Use native Mac document tabs with filenames, active-tab highlighting, and double-click closing.
Keep project navigation shared while each document retains its own editing and preview state.
Preserve unsaved edits during external-file refreshes and exact JSON values when formatting.

Double-click a native Mac document tab to close it, with the existing unsaved-change confirmation.
Makes native document tabs standard for macOS, replacing the previous in-editor tab strip and experimental setting. Native tabs show filenames, highlight the active document, and share the project sidebar without sharing document contents or preview state.
Keeps the newer touch-friendly UIKit tabs standard on iPhone and iPad, and preserves visionOS's existing tab experience.
On iPhone Duo, moves the editor toolbar into a vertical column on the right edge, below the status bar, when the phone is closed, open, or partially folded, so it no longer covers the bottom of your document (#498).

Keeps the Mac editor at full height when the code minimap is shown; short Swift, YAML, and other code files no longer collapse to a single centered line.
Adds space between the Mac toolbar's outer symbols and the rounded ends of their group.
Gives the first Mac tab the same toolbar background as every other tab.
Keeps each Mac tab's cursor, selection, and preview independent, so typing in one document no longer refreshes other tabs.
Keeps project Markdown cards shared across Mac tabs, preserving prepared previews, pane width, and scroll position when switching or opening documents.
Restores Mac tabs without briefly showing separate windows, keeps file-conflict prompts with their own document, and preserves unsaved-change protection when closing.
Rechecks document revisions before applying external file refreshes, so edits made while a refresh is pending are not replaced by stale content.
Keeps Safe Mode's blank editor in its original window and keeps recovery drafts separate from the normal saved session.
Preserves JSON object member order, repeated keys, exact number tokens, and escaped strings when formatting or combining lines (#802).

The previous Mac in-editor tab strip and experimental native-tab preference are replaced by native document tabs. iPhone, iPad, and visionOS retain their existing platform-specific tab experiences.

No document conversion is required. Existing saved sessions use the native document-tab layout on macOS.

Hides the content of unselected native Mac tabs so their rendering surfaces can be released; in the paired benchmark this kept retained memory close to 2.0.0 while tab switching stayed faster than 2.0.0.
Removes the retired in-window Mac tab code paths and the unused "Open in Tabs" setting.
Builds native Mac toolbars once per document, starts file loading before window setup, and defers inline Markdown preview and the language menu until needed.
Adds a disposable native-tab benchmark harness with display-state logging, titlebar parity, pane-height, and Markdown rendering checks.
