Tables
You can re-size columns in a table to accommodate a shorter or longer header length. To change the width, hover your mouse over the vertical divider line in the column header. Your cursor will turn into a double arrow. Click and hold on the line to drag it to a new position.
In general, double-clicking on a row will open an edit dialog.
Adding Multiple Records
Clicking Add in a dialog box will add the record you just created, but the dialog remains open. This rapidly creates multiple records without having to re-open the dialog each time.
