I used JBuilder IDE quite a long time and always missed some functionality. Here you can find the add-ons I've developed for this great Java IDE.
This module adds a "Navigator" tab into the Messages frame in the bottom of the JBuilder window. The "Navigator" panel can display all the classes you need to work with at once. No more scrolls on Project view, and you can switch to the any method you need just one click.
