But U can add them in your UI, but U should disable them and mention them in your Doc the reason for adding them.

I would NOT put widgets for the add/delete functionality for the UI. If they are permanently disabled, you will lose points for violating standard HCI princples. What I did was implement add and delete, and verify that they worked correctly using
Unit Tests, but never actually call them from the program itself nor put any UI for them in.
