Add an option where you could make a shop that has a limited time offer, where the listed items to sell are available for a specific time

where you are able to make lists, list1, list2 and so on...

List 1 will be available for example 3 hours

after 3 hours it will hide list 1 and display list 2 for a specific time

and after list 2 time ends it will go back to list 1 or other lists

this could be used for events and many things

This can already be achieved with the snapshot feature (see the snapshot commands) + some third-party command to run commands in specific intervals: You can create shopkeeper snapshots for your different trade configurations and switch between them via command. Running commands in specific intervals is rather generic, so this aspect is better fitted to be implemented by a separate plugin.
