- New Library… from the menu asks for a name (default prefilled), then the location.
- The open library's name shows under My Photos in the left panel (hover: its path), so it
is visible on macOS too, where the window title isn't.
- Switching also remembers the library being left (e.g. the one opened at launch).
- whats-new entry and parity row LRC-LIB-CATALOG-SWITCH.
