Each Abtrac user can choose how their timesheet looks like.
Linear Timesheets are line by line, with dates on the left.
Cross Tab Timesheets group similar entries together, and have dates in a table on the right.
In both types of views, you have the choice of entry through either the form view or grid view. With all views, you can show, hide and change how you see the columns, in the user control settings pages.
