I would like to directly export filter results to an email, rather than save the filter&create a subscription for it. I guess this option does not exist now, where could I open a ticket with such request?
You could share the filter result just via mail. The mail reciever will get a link to the issue navigator with you query. (You don't need to save the filter).
If that is not what you need you can file a feauture request here:
