Choose your preferred mobile context view method and make sure it is easy to access.
Make sure your context views work for all active tasks regardless of other ways you may classify your tasks. For example, if you use folders for contexts and you create (Work) and (Personal) folders, but this prevents you from seeing (Work) and (Personal) tasks in your Errands view, then you cannot use the folders feature.
(Only if required.) If you need to define and save custom views, do that now for each major context, common 1-1 contexts, meeting contexts needed on your phone, and action contexts you may need to see on the road (like Errands and Calls).
