In the Projects window, expand the Configuration node in the project you want to modify, and then double-click midm.xml.
The file opens in the NetBeans XML editor.
Scroll to the source-record element (located in the gui-definition element).
To specify a different name for the Source Record tab, modify the value of the tab-name element.
To change the order in which the Source Record tab appears on the MIDM, change the value of the display-order element.
You might need to renumber the remaining tabs to keep the numbering sequential.
Save and close the file.
