Menus, zoom, and startup
The native menu bar, persisted zoom, launch at login, and tray behavior.
Zoom persists per machine
Zoom applies a CSS zoom factor to the page — the same mechanism across WKWebView, WebView2, and WebKitGTK — bounded between 0.3× and 3.0× in steps of 0.1. The choice persists in a zoom-state.json sidecar in the app config directory and mirrors into the page's per-origin storage, so it survives restarts and reloads alike.
Launch at Login and the tray
Launch at Login registers the app in the operating system's startup list, and the checkbox mirrors the real OS state rather than an assumed one. The tray icon menu offers Show Supastack and Quit; a left click toggles the window — hidden or minimized means show and focus, focused means hide.
Verification and troubleshooting
Walk each menu on the target OS: accelerators must fire inside the webview, zoom must survive a restart, the beta toggle must stay disabled without a channel-capable feed, and the tray left-click must summon then hide the window.
