Show / Hide Columns

The Column area is the section to the left of the schedule that lists the data for each task. You might find that some columns are useful and others are not. You can hide the columns that you don't want to see and show the ones that you do want to see. To do this, click on the Column title bar in the area shown below.
This will display a list of all of the available columns in the system. You can check and uncheck the boxes to show and hide columns respectively.
Moving Columns
If you have the right columns displayed but you want to change their order, then simply click on the relevant column header (shown in the screenshot above) and drag it to its new location (i.e. to the left or right). When you drop one column on top of another one, it will automatically update the order displayed.
