with the htc people widget, if you press the three bars at the bottom left on the widget, it brings up all your contacts. then press the magnifying glass soft key on bottom right of your phone to search. The people widget definitely does have a lag, especially if you add a lot of contacts to your favorites. i have found if I only make a few contacts as favorites and using the smaller people widget, there isn't as much lag,
Or you can put shortcuts to a particular contact(s) anywhere by long pressing on blank screen, selecting shortcut > person and then selecting contact you want to make a short cut to. This will only make a shortcut to one person.
or if you want a shortcut to all your contacts, just long press>shortcut>program>people
