Lennart always says he’s going to work on it, but he’s a busy man and nothing has actually happened.

It’s a pretty easy feature to implement I think.

Once Lennart convinced me of the usefulness of this [1], I've been finding plenty of places where I wish I had it. Who's working on it? What's the status? Is there a ticket for it?
