Let's say I want to search for users with email from a specific domain. I go to the search user page and type in the domain and get a list of those users. I want to delete them all. I click the 'X' and confirm the deletion, but it takes me away from my search results when it finishes deleting the user. I had more users I wanted to take action on - don't make me hit the back button, take me back to my search results.
*facepalm* I suppose I should try and upgrade to 1.2 soon - forgot about the bulk management features being added.
Either way, I'll stand by this suggestion for instances when I'm not doing bulk management, but still want to return to my initial search.
