While I believe that it is a no-brainer, that one should be able to label Elements in the list view, I also think it must remain optional. That heading and elements by default show the text of the heading might work for some people, for others maybe not (I, for example, find it rather annoying). One must be able to choose to keep the labels generic — what is so hard with adding an option in the editor preferences?

However, I really hope the option to individually label any list element you want will come soon, I totally miss it, every day (anyone knows if there is a plugin out there for this, in the meantime?)
