I think what is meant is that text objects are automatically named with the first x chars of the actual text and that all other objects can be named from the layer/object gallery.

This would indeed be useful, however, it might be tempting to name every object, even those for which a name isn't necessary - when I mean necessary I'm hinting that one needs to consider what names are currently used for - e.g. slicing, buttons etc.

Changing the naming policy might break file compatibility with previous versions of xar files - just guessing here. I've always been thankful the Xara's file format has been consistent from version dot.

However, all things considered - I wouldn't take PS's layering system as a good example of anything, but a combined name/object gallery would please me.
