Stream Deck turns the things you do all day — open an app, a URL, a project folder, a shell script, a System Settings panel — into one-click buttons in your menu bar. The menu bar isn't a convenience here, it's the whole app: LSUIElement is YES, so there's no Dock icon and no window to switch to. Click the icon, the deck drops down, you click a button, it fires, you're back to work. A second entry point — a draggable floating tab you can pin anywhere on screen — opens the same deck on hover.
