There is another report hidden away in this application which is quite useful, and you'll be glad when you find it. Click on "Projects", and under "Selected projects" click the "Timeline" link next to "Add project". Under the project column you'll see each project you're working on, and based on the estimated start and end times, the timeline will display bars so you can see which projects overlap, and thus when thinks might be more rocky, or conversely when you have time for some new work.
