It would be great to include the poosiiblity to rename the objects such Menu1, Title1 and so on. That would ease the DVD design.
For example, I (try to) make a DVD with picture"s diaporama. The pictures are grouped in category. But the tiles are not so helpful to determine the group I would like to link a button to. Allowing us to rename "Title 1" to "Halloween" (and keeping "Title 1" for DVDStyler internal use) would ease to recognize the group of pictures.
(I hope I was clear enough)
