Another small one: the main window learned to come back.
Fixes
- Reopenable main window — closing the main window used to leave no way to get it back short of relaunching (⌘N makes playlists here, like Music, so there was no "New Window" either). The window is now a proper single-window scene: macOS lists Hydrophone in the Window menu, so a closed window is one click away. The menu-bar mini player keeps working the whole time, window or no window.
Install: unzip, drop in /Applications. Signed & notarized — no Gatekeeper warnings. Requires an OpenSubsonic server (Navidrome, Gonic, LMS, …) or try the built-in demo server button.
