Field notes
Backpane is presented as a menu-bar AppKit utility rather than an Electron app. Its notes can be plain text or Markdown with front matter, and the page says they follow documents in Xcode, VS Code, Preview, and TextEdit when those files are reopened. An All Notes view supports search, detaching, deletion, and export. The stated offer includes macOS 15 or later support, Apple Silicon and Intel builds, a seven-day full trial, and a fourteen-day refund window.
