[Inkscape-devel] object properties

I notice the Object Properties dialog has changed. Questions:

Why are Title and Description always disabled?

What is Label? It's made from the id obviously but pressing Update informs me that it is "invalid". Hey, I did not put it there! Why Inkscape gives me something which he (Inkscape) knows to be invalid?

Most importantly, where did the id= field go? We must keep a way to edit id, even if we add more stuff to this dialog.
