Hidden smart group does not update when mailing is sent or opened unless smart group cache cleared
When you create a mailing to send to a set of contacts from search results, this is displayed as a "hidden smart group". However, this group is just a set of contacts that you select, not actually a smart group (i.e. it does not update based on the search terms used). One of our staff members had been assuming that it would update as it is a "smart group". Maybe smart group makes sense from the backend, but for a user, it is confusing to use smart group when it is actually not a smart group in the sense that matters.
I propose changing this to "hidden group".
I believe the text should be changed here.
