I want to browse recent, open bugs. All of the bugtrackers that I have seen up to this point made is difficult to do 2. Most of the time they use poor language like 'generate reports'. I find that bug IDs are the last thing I remember and I think it's an extremely poor choice to be presented to a new visitor. My interface reflects this disatisfaction.
All major actions are available via the menu bar, thus navigation is simple and quick.
