SeatKeeper par Artllex

SeatKeeper remembers your favourite cinema seats and helps you select them again on auditorium seating plans.

Supports European cinemas — current integrations cover Polish booking websites: Multikino, Helios, Cinema City, Kino Spektrum, Gdyńskie Centrum Filmowe (Gdynia Film Centre), Kino Muzeum II Wojny Światowej (Museum of the Second World War cinema), Instytut Kultury Miejskiej (City Culture Institute), Cinema One and Kino Nowe Horyzonty (New Horizons Cinema). Supported profiles include cinemas in the Tri-City area and Wrocław, including Multikino Gdańsk, Helios Forum Gdańsk, Helios Gdynia Centrum Riviera, Multikino Wrocław Pasaż Grunwaldzki, Cinema City Korona and Kino Nowe Horyzonty. Coverage depends on the supported booking page and auditorium detection; the extension does not automatically support every cinema in Europe.

• Save favourite seats per cinema and auditorium.
• Calibrate with F8 and automatically select saved seats where supported by the seating plan.
• Search settings and export/import JSON backups.
• Dark interface with Polski / English selection in settings.
• No preconfigured favourite seats — choose your own.
