Newbie Question: Resources...

I am new in QNX6, but I have few questions to PhAB developers :

  1. Why is not present possibility of calling by user from own code next
    -Number Editor
    -Text Editor
    -List Editor
    (These dialogues are loaded for editing resources in PhAB)

  2. Location Dialog
    Why is impossible to add new location: “At Centre of Parent” ?
    It would be very convenient.

Best regards,
