When creating a new list of tasks for a job, be careful to keep the description simple so as to see it better on the Task Bar in Gantt View (e.g. Rather than saying Install Hardwood, say Hardwood Install). When viewing the task in a one week view you can see the description on the task bar easily. As you expand the view over longer time frames you will see less of the description on the task bar.
Tip: while mousing over a task, check the status bar at the bottom of the screen to see the detail of the task.
