vorssaint/vorssaint-utils ? reverse-engineered prompt

Build me a macOS menu bar app that puts a bunch of useful system tools into one small icon. I want it to feel like a polished all in one utility for Mac users, with things like a per app volume mixer, system monitor, better app switching, window snapping, clipboard history, text snippets, a file shelf, and an easy uninstall tool.

It should be modular, so people can turn individual features on or off and only load what they use. The app should stay private by default, work fully on the Mac without accounts or telemetry, and keep settings if a feature is turned off and later enabled again. Please make it support a clean settings window, a compact menu bar layout, and a first run setup that helps users pick a few bundles or individual tools.

Use the current macOS design style, and if you need anything specific, look up the latest Apple docs before coding.
