Being able to deploy pop ups through the tag manager is really useful, and a fantastic feature.
It would be great if the pop ups could come with some additional controls around the closing behaviour. It is challenging to configure a mechanism to stop showing the popup to someone who has closed it, or indeed not show it for a certain period after it has been closed.
Being able to easily do this would prevent constantly showing a pop up to someone who has closed it, but is challenging to accomplish at the moment.
