My sugestions are:
1. Use geotag to show the tasks when you're in home or at work. Based on the tag that you set for these places, doit.im shows the tasks that have the contexts @home and @work for today;
2. Use the web/phone app to do the same thing when you access them but, to the tasks with the contexts @computer and @phone;
3. Integrate with IFTTT like Todoist and Toodledo to have triggers with apps like pocket, gmail and others;

Well, i think that improves the app very much. Sorry about the poor english lol.
