System for letting people know if the if the cafe is open

[Sebbben]

I miss a way of knowing weather the cafe is open or not.

I imagine having a simple page that simply displays if the cafe is open or closed and an accompanying page that the shift master can use to declare the cafe as open.

When opening the cafe, the shift master can open an app either on their phone or on the cafes ipad or the dj pc and simply navigate to the site and set a closing time and press an "open" button which triggers the update of the open/close page
