I should clarify, what I am trying to do is add entire sets to my collection at once. I'm not even sure if the card actions button will let me do this. Basically I want to nominate the sets by using the advanced search, which works fine, then click the select all button and add one of each card to my collection. Is there any way I can do this?

This is broken for me as well - works when using the widget but when I want to filter certain sets and add them all at once from the card database I can't because clicking the card actions button does nothing - have tried on both IE and Chrome..
