The ability to open and close your store can be very useful for limited product sales. Just like having a physical store where you have an open and close sign.
If there was a feature whereby you can set a countdown clock and when the clock zero's the store would open/close (depending on the users requirements) this could be reset whenever the owner requires.
This could be useful for Online Tickets, Limited Edition Stock or Ordering windows to collect orders before ordering in your stock.
How it could look/work
Window with Store Details. This would have a slider for store 'Open' or 'Closed' that would show on the store or change 'Add to Basket' to 'Store Closed'
On this window there would also be the clock that you can 'Add to Site' once added you can select the time required (all from the dashboard). Then an option to select what happens at Zero or required count up time. 'Show a Message' 'Open/Close Store' 'Show an Image'
