Overview

Built a native macOS menu bar app in Swift that hides the icons you do not need, as a free alternative to Bartender.
Built for macOS 27 and working on macOS 14 and later, on Apple Silicon and Intel.
Handled two different mechanisms: a stretched divider on macOS 14 to 26, and per-app visibility through macOS itself on macOS 27, where the old trick no longer works.
Added auto-hide after a few seconds, a quick panel on right-click and open at login.
Set up a release workflow that builds a universal app, signs it with a Developer ID certificate, notarizes and staples the DMG, and updates the Homebrew cask.
Distributed through GitHub releases and a Homebrew tap under the MIT license.
