Ctrl-F lets you search for contacts in your rosters. The other two shows your recent and favorite contacts. But those dialogs only allow you to double click the result and start a chat. What i miss, is a context menu. I want to be able to right click on a result of that dialog and get usual context menu of a contact in the roster. Often i want to get a notification about some user getting online (Alert when user is available). But i always have to dig that user in the huge roster and groups to be able to right click it and select that option. Not very productive. Would be a lot faster to press Ctrl-F, type a few letters, right click the contact and select Alert when user is available. There could be some other scenarios with moving, copying contacts, sending files, viewing profiles and history or doing some other stuff.
