Very simple and useful

One little request — Allow editing the module after the content expiration time without having to set a new future expiration time.

For example, if the module expired a few minutes ago and then I see a typo in the expiration message, I can’t make the change and re-save the module unless I set a (new) future expiration time.

I think it should allow you to save or re-save the module as long as the expiration date is after the start date. As a further refinement, if the expiration time has already passed, it could just prompt you with a message: “The expiration time has already passed. Are you sure you want to save your changes?”

Good work with this and all your other modules!
