Examples Recommender: an Eclipse expert looking over your shoulder, ready to help Test Reminder: help users to manage and build testing plans

User study We are looking for users’ interactions to understand how they are using their IDEs to help us build more powerful applications. Help to find out what’s the difference among different users to finish the same project?
