Ability to search contacts across all addressbooks
I have multiple local and online addressbooks, which allows me to compartimentalize cleanly my personal vs professional lives vs other projects, and also lets me selectively sync some addressbooks depending on the device.
However, there's one issue: half of the time I search for a contact in addressbook B, while it's in addressbook A or C, so I have to clear the search, switch addressbook, search again, see if I get results, rinse, repeat.
Like for email, I would like to have a combobox on the right of the search field that allows me to search either "in [Current Addressbook]" or "in [All Addressbooks]" (and it should remember my choice).
