In the iPhone app, if one uses the search box at the top of the app to look up a call sign, information about that person is displayed. It would be nice to have a “log QSO” button in that view to avoid having to switch to the logbook view (and re-entering the call sign). I guess there might be an issue around which logbook to use (when one has multiple logbooks can one be set as the default?).
I started with the iPhone app for WFD today, but switched to the iPad because it felt like I couldn’t keep up with the QSO flow on the iPhone.
