Tree is always collapsed after loading

If I change a slide and save it the loading screen is shown. After the loading screen disappeared I see my slide and the tree on the left side containing the decks and slides and so on. But the decks in the tree are all closed and only the decks in which my current slide is located are opened. This is a problem if I want to see the slides of other decks inside my presentation because I have to reopen them every time I save something.

It would be great if the user interface could remember which decks have been open so it could recreate the state before I clicked the save button.
