Problem

Updating the app icon images (AppIcon-Source.png / AppIcon.icns) did not change the menu bar icon, because the menu bar status item was never derived from the app icon. In Sources/App.swift, the idle glyph was either the SF Symbol waveform (release build) or a hand-drawn rounded-square-with-bars (StampedMenuBarIcon, dev build).

Fix

Replace StampedMenuBarIcon with FluentMenuBarIcon: a monochrome template glyph that mirrors the new brand — a speech-bubble ring with a flowing waveform inside.

• Used for the idle state in both release and dev builds, so the menu bar now reflects the new identity.
• The dev build gets a small marker dot so it stays distinguishable from a release build running side by side.
• Recording / transcribing keep their record.circle / ellipsis.circle status icons.

Why a template (monochrome) glyph, not the colorful icon

Menu bar items should be simple monochrome template images so macOS can tint them for light and dark menu bars. The full-color 3D app icon (with its white rounded background) would look wrong in the menu bar, especially in dark mode. AppIcon.icns remains the dock/Finder icon.

Tested

• swiftc -parse Sources/App.swift passes. A full build needs the macOS SDK (not available in this Linux sandbox), so please run make run CODESIGN_IDENTITY=- and confirm the menu bar glyph looks right at 1x/2x in both light and dark menu bars. The bezier coordinates (ring radius, waveform peaks, tail) are easy to nudge if you want the silhouette tweaked.

Summary by CodeRabbit

• New Features

  • Updated the menu bar icon to better reflect app status, with distinct visuals for enabled, recording, and transcribing states.
  • Introduced a refreshed default app icon for the menu bar, with a subtle visual marker in development builds.

• Bug Fixes

  • Replaced the previous menu bar icon rendering approach with a more consistent, streamlined version.

📝 Walkthrough

Walkthrough

Menu bar icon rendering now branches directly on app state for enabled, recording, transcribing, or idle states. The idle icon comes from a new FluentMenuBarIcon image generator, and the previous stamped icon implementation was removed.

Changes

Menu bar icon rendering

Layer / File(s)	Summary
State-based icon selection and custom idle image Sources/App.swift	MenuBarLabel now picks a checkmark, recording symbol, transcribing symbol, or a templated FluentMenuBarIcon image from app state; the idle icon generator now draws the menu-bar glyph with NSBezierPath and an optional dev dot.

Poem

A bunny hops by, ears held high,
Three little icons wink in the sky.
Ring, wave, and dot in a tidy row,
For quiet menus and swift hello.
