I think the UI needs attention most. I want to use it, but I want the searches to be done at once, so I can just skim across the sources. Maybe on hover-over?

I think the UI needs attention most. I want to use it, but I want the searches to be done at once, so I can just skim across the sources. Maybe on hover-over? It would also be good if adding a new engine were easier. The language is a bit confusing. I think there should be an explicit "add another search provider to this list". Keep it up! I'll be checking back!
